This reverts "Attempt to optimize file counting." and related commits.

(commit c257429c561af8b99bb0a0daa65871a80a9fedb2)

Two executions of 'git-rev-list' were merged and python used instead of sh
snippet. From initial testing this seems to _slow_ things down.

Hopefully fixes a problem with linux-2.6 repository.

Earlier this borked on author names containing "," (or example, wine
repository). Now it will instead check for line containing "files changed,".

Removed an extra "git-rev-list".

For now it's taken from the basename of the repository path.

Get total lines of code from "git-log --shortstat" instead of "cat".

Line statistics are gathered correctly (again).

Headers are now created using html_header() function.

This name change was done just in case the statcvs/statsvn folks plan on making
a git version at some point in the future (the projects seem to share
developers).
