slightly clarified the "license" portion of `README.md" + formatting all over

There are commercial open source applications, hence proprietary seems to be a better term.

Also:
 - Trimmed header `=`'s to match text length
 - made libgit2 stand out everywhere
 - pretty printing links
 - irc link for those with the correct setup
