[PATCH] cvsserver: Document the GIT branches -> CVS modules mapping more prominently

[Frank Lichtenheld <frank@lichtenheld.de>]

Add a note about the branches -> modules mapping to LIMITATIONS because
I really think it should be noted there and not just at the end of
the installation step-by-step HOWTO.

I used "git branches" there and changed "heads" to "branches" in
my section about database configuration. I'm reluctant to replace
all occourences of "head" with "branch" though because you always
have to say "git branch" because CVS also has the concept of
branches. You can say "head" though, because there is no such
concept in CVS. In all the existing occourences of head other than
the one I changed I think "head" flows better in the text.

 Caused by me thinking about Junio's comment.
 Better patches welcome but my motivation to try to write clear
 and concise sentences in English is depleted for now,
 so no critical comments without patches, plz :)
