A little patch to give a reasonable version number when building
prosody, for those who work with git as their VCS front-end. Details
are in the commit message.

Subject: [PATCH] Makefile: git-based version number
In cases where someone is using a git front-end for VCS, will generate
a prosody-version file based on the git HEAD commit hash. If that git
front-end repo is bridged from a hg backend repo, will also append the
latest hg commit hash. Those not using git as their VCS front-end
will not be affected, nor those building a 'release' version.
Also notices if the local working tree has been modified from the
latest git commit and indicates accordingly.
A typical version number would then look like:
git:157cb4b7/hg:3849b5187d47
Or for a modified local source tree:
local:dirty/git:0205d863/hg:3849b5187d47
The old behavior was to call the version "unknown".
