Make git-describe faster if no git index files have changed Running "git commit" in core and xml touches .git/index and .git/modules/library/xml/index, respectively, so if neither of those have changed, neither has the git information we care about, so avoid running git entirely (which can be slow sometimes).

git-describe.cmake: use 8-digit git commit abbreviations The length here was previously determined automatically, and jumped from 7 to 8 recently, breaking devel/check-release. Since Git seems to think 8 characters is better now, specify it explicitly to avoid future breakages.

Add git commit information to libdfhack-version git is run every time 'make' is run, but the generated include file is only updated when necessary. Plugins will be loaded successfully if their DFHack version matches core's (assuming OpenLibrary() succeeds), but will produce a warning if their git commit doesn't match core's.
