TODO
- make nice login page
- implement toXml for Rooms and Sprites
- user accounts so that people can
  - save rooms, sprites, generators to the server
- correctly handle rooms larger than the view area
- teleporters
- maybe monsters and treasures and stuff?
- hide ability to start the game by teleporting into any room, as this
  allows people to jump right into other people's stuff.
- need some sort of game engine abstraction maybe?
User-submittable things
- New Tilepals
- New RoomGenerator / TerrainGenerator classes
  - more flexible function model
  - caves?

2005-10-21c
- added alternative cookie-based authentication for logins
- added disown room command (U)
- added doc/userguide.html and link in main menu
- added some new heads
- added some new worlds (def2, infworld5)

2005-10-21b
- removed those useless .xcf files
- issue a warning when response from saving a room or sprite uses
  unsupported transfer encoding instead of letting exception go.
- Hosting problems. I didn't relize this would be so tricky. Ack!
  - io.uwplatt.edu uses a crappy version of PHP (4.2.2) that seems to
    offer no way to handle PUT requests. It also gives me
    chunked transfer encoding all the time which sucks.
  - sourceforge mounts everything as read-only for the web server
  - my DSL is too slow for me to host it myself

2005-10-21
- Completely reworked the PHP UI pages - you can now create user
  accounts, mofidy accounts, and log in and run around with the
  settings you set.
- Added some nice vegetation tiles.
- You can use control to pick blocks, not only alt (for consistency
  with GIMP, mainly)
- Tiles with the foreground flag are placed in layer 1, if there is
  one, when placed by the user clicking.
- Added the dig command so players can tunnel through mountains and
  across oceans easily.

2005-10-20
- Added roomReplaced event to RoomEventListener
  - a more general event than CacheEventListener#roomReloaded
- Cleaned up the user interface a bit, especially regarding
  the way tiles are selected, which has been much intuitivized.
- added useless prototype 'D5.2 Keys' window (opens when user hits F1)

2005-10-19
- Rejigged a lot of things in D5Applet
  - Added tilepal display and ability to choose and place tiles
    - messy code, fix later.
  - Reworked the way D5Applet is notified of room changes
    - more things are event-based
    - still a but messy, needs more reworking, performance decreasing

2005-10-18
- Streamlined the process of saving worlds, as
  - xml made by customroomgen.php now includes worlddesigner-params and
  - worlddesigner.php reads the roomgens dir for presets
- fixed a bug in Room#fromXml (tile ids were always read as hex)
- fixed teb.js to allow non-empty teb elements (image is now inserted as first
  child element)
- rejigged Sprite#wantMoveDir business. At least it is more flexible, now.
- blockall now means (according to Cell#getBlocking) no entry/exit from
  *any* (including diagonal) angle.
- user-id, title, doc are now generic 'properties' of rooms.
- fixed a fencepost error in Cell#getNeighbor

2005-10-14
- Room#toXml implemented
- can upload rooms to the server, which does not yet do any authorization
  checking
- added HttpClient class, which seems to work decently
- no way to actually change rooms from D5Applet

2005-10-12
- Moved xml parsing into respective classes, out of ResourceCache
- RoomGenerator changed to BasicRoomGenerator
  - RoomGenerator is now an interface
  - Different RoomGenerator classes may be specified

2005-10-07
- TerrainGenerator selection more modular
  - TerrainGenerators can be added simply by adding *TerrainGenerator.php
    to the phplib/d5_2/gen directory, and by adding a *TerrainGenerator.class
    to classes/d5_2/gen.
- Positions are always specified by pos="x,y" rather than x="x" y="y" in
  serialized parameters.
- Re-jigged the PHP side of things a lot including
  - relatively user-friendly 'start new game' page (playersetup.php)
  - separating more functionality into phplib/*
  - xml for generators is now gotten by requesting from 
    data/roomgens/customroomgen?sameparamsasforworlddesigner

2005-10-06
- Fixed bug in tilepals/outdoor1.xml where cliff tiles were not blocking
  (an old version had snuck in there somehow)
- Pushed around complexity relating to ResourceCache and the clearing thereof,
  e.g. Sprite#fixRoomRef( rc )
- Removed RhinoTerrainGenerator for its uselessness.
- Diddled the PHP a lot. worlddesigner.php now makes more sense, I think.

2005-10-05
- Added scale parameter to NoiseApplet
- Changed 'zoom' to 'scale' in RoomGenerator
- RoomGenerators now use a NumberGradient to map terrain type
  samples to tile ids (this is the second column of <terraingradient>,
  the first column being colors used for the ImageGenerator
- Added coordinate indicator and click-zoom to NoiseApplet
