[gaim-migrate @ 11141]
Two things:
a. Added Enter as a gtk_binding to GtkIMHtml. This fixes everything.
Input methods now work. The "Enter sends" and "Ctrl-Enter sends" preferences
were removed and defaulted to yes and no respectively, BUT, in a very super-cool
turn of events, you can now add your own bindings to .gtkrc to make WHATEVER
YOU WANT send. Awesome. Someone should use g_signal_accumulator_true_handled
or something to make profiles and away messages able to insert newlines.

b. Removed "Use multi-colored screennames in chats," defaulted to yes, and
wrote a nifty algorithm to automatically adjust the colors to accomodate the
background (see http://gaim.sf.net/sean/porn-chat.png). People should play
around and tweak it a bit. The algorithm takes into consideration the
luminosity of the current background and the base hue to use for the screenname
in generating the new colors. Note that it does this while maintaining the hues.
Someone should optimize this so it skips over the floating point arithmatic when
the background color is white.

Notes on keeping GAIM OS independant
------------------------------------

General
-------
- Use G_DIR_SEPARATOR_S and G_DIR_SEPARATOR for paths

- Use g_getenv, g_snprintf, g_vsnprintf

- Use gaim_home_dir instead of g_get_home_dir or g_getenv("HOME")

- Make sure when including win32dep.h that it is the last header to
  be included.

- Open binary files when reading or writing with 'b' mode.

  e.g: fopen("somefile", "wb");

  Not doing so will open files in windows using defaut translation mode. 
  i.e. newline -> <CR><LF>

Paths
-----

- DATADIR, LOCALEDIR & LIBDIR are defined in wingaim as functions.
  Doing the following will therefore break the windows build:

  printf("File in DATADIR is: %s\n", DATADIR G_DIR_SEPARATOR_S "pic.png");

  it should be:

  printf("File in DATADIR is: %s%s%s\n", DATADIR, G_DIR_SEPARATOR_S, "pic.png");

PLUGINS & PROTOS
----------------

- G_MODULE_EXPORT all functions which are to be accessed from outside the
  scope of its "dll" or "so". (E.G. gaim_plugin_init)

- G_MODULE_IMPORT all global variables which are located outside your
  dynamic library. (E.G. connections)

  (Not doing this will cause "Memory Access Violations" in Win32)
