tremulous: chat and colors overhaul (#108)

* tremulous: chat and colors overhaul
- Implement new message modes with the say menu for admin and clan chats.
- Implement support for custom colors defined through a hexadecimal format,
  include both a short and long format for the hex support, that is ^#fff and ^##ffffff.
- Remove extra color codes that are unused in player names.
- Implement an escape from the color escape so that ^ can be printed by typing ^^.
- Make it so that the length of names are minimally effected by the use of color codes.
- Fix the display of colorful names in the HUD kill feed.
- Have the printed line width in the console adjust with the resolution.
- Implement 62 hardcoded standard chat colors.
- Implement the command /colors
- Have editable text fields preview colors while editing.
- Implement an input history for the say menus.
- Implement cycling through message modes with page up and page down.
- Initial implementation of player mentions, and player tab completion in
  the say menu.
- Have ctrl+c clear the current line of the say menu, when the say menu is open.
- Make arrow down at the current line in the say menu clear the input, but if
  a writable key isn't pressed, don't completely delete the current line
  behind the scenes to allow up arrow to recover it.
- When the say menu is exited with unsubmitted text, the next time the say
  menu is open, it would be in a pending blank state where you can recover
  the unsubmitted text with arrow up provided you didn't already press a
  printable key.
- In the console make colors that are too dark appear brighter in the
  console so that they are more readable.
- update .gitattributes
- new version of curl curl-7.68.0 incompatble with code, so pointed to local headers for linux build
- engine: add footer labels for the color list for the command /colors.
