Explanation of build version:

> BUILD_VERSION=`git log --oneline | wc -l|tr -d ' '`-`git rev-parse HEAD|head -c 10`
> 
> This produces a version of the format `<commit count>-<unique hash>` satisfying the approximate magnitude of change and providing an easy way of determining newness (barring any incidents of force-push rebase operations). Version 4123-2f1df15079 is going to be newer than 4007-fc036c4ee0, sorts properly when using most sorts, and (due to the hash value) guarantees that if versions are produced independently (say by two different developers) they will not have the same version.
