Get LOC and SLOC for a file at every revision

[andymeneely]

We need a script that does this:

• For each revision (yes, all 26,000 of them)
• Do a git checkout on that revision. (Or maybe just a tree lookup using git tree? might be faster)
• Get the SLOC counts on the files affected by that revision. Use CLOC for this (http://cloc.sourceforge.net/).
• Dump this to a parse-able text file.

If it's slow, only go with .c and .h files.

Parse that data file and update the GitLogFiles table with a new field for all of these.

In the end, we need the Churn / LOC. SLOC we might need someday, but not for this particular study (yet).

Ok - got the code now. I've done some refactoring. See the upcoming commit.
