[ANNOUNCE] tig 0.4

Hello,

Too many improvements to keep me longer from releasing version 0.4 of tig, the text-mode interface for git. First off, a big thanks to Aneesh Kumar for helping with improving the basic user interface. Among the highlights, colors are now configurable in ~/.tigrc and the diff and main views are better integrated. For more info, changes I feel are most important can be found below.

I hope to focus more on fixing some of the accumulated bugs for tig-0.5. A particular embarrassing one, is the problem with text wrapping for long lines which can end up corrupting the screen. But there should also be room for a first shot at displaying revision graph and maybe configurable keybindings.

A list of tig resources:

 - Homepage: http://jonas.nitro.dk/tig/
 - Tarballs: http://jonas.nitro.dk/tig/releases/
 - Git URL:  http://jonas.nitro.dk/tig/tig.git
 - Gitweb:   http://pasky.or.cz/gitweb.cgi?p=tig.git;a=summary

Tarballs contain all the generated documentation, as do the #release branch of the git repository. Thanks to pasky for the gitweb hosting.
