Commits in projects with lots of activity and authors don't happen
chronologically (patches are accepted later etc), so the counting was messed up
for them (git.git for example).

This was supposed to be part of the last commit.

Todo items for another project... :)

Shows how many days the author has done commits on.

This allows installing in other locations besides /usr.

This prevents tics like 1.75, 2.5 etc on file count / y-axis.

Reported by Anonymous on SourceForge bug #2892604.

Allow piping into a log file more cleanly without spewing \r (on Linux which
supports os.isatty()).

Some of these were pointed out by Anonymous on SourceForge bug #2830659.

After this change the CSS validates on jigsaw.w3.org.

Reported by Anonymous on SourceForge bug #2886542.

The first path to be searched is the directory of the binary, then
/usr/share/gitstats/. This is so that you can have both a "global" gitstats
version and a user-specific checkout installed, and the static files should be
taken from the matching place.

This change is done in preparation for Debian packaging.

Vincent Fourmond <fourmond@debian.org> is planning to package gitstats for
debian (RFP #440392).

This seemed to be roughly three times slower than a direct "wc -l" from working
tree, but this way we are not limited to full & clean working trees, but can
also handle bare repositories.

Instead of 'w histeps', we use 'w steps', which doesn't make the last commit
seem like it removed all the files.

A simple assumption is made about the tags: it's assumed that they come in
chronological order, and share the same history (eg. v0.0.1, v0.0.2). That way,
to get commits made for v0.0.2, we simply look for history from v0.0.1 to
v0.0.2.

Month was used where minute was supposed to be... wrong case :)

Currently taken from "git rev-parse --short HEAD".

Gives better proportions on amount of commits during each year.

'smooth csplines' showed negative file count sometimes, which wasn't nice ;-)

This closes bug #2184326 on SourceForge. Some people may not have access to
their git repository, so we save the cache to the output directory instead
(which must always have write access anyway).

Don't consider .hidden files extensions, and limit extension length to 10.

Just in case they have been updated.

This sorts tables on the authors and files pages.

Slightly modifies the sortable.js to ignore additional info in
parentheses after a number.

This adds the sortable table JavaScript from
http://yoast.com/articles/sortable-table/ (version 1.5.7) and some
helper images from the same site.

[hoxu@users.sf.net: The license linked from sortable.js and the one linked from
yoast.com (to opensource.org) differ a bit (the middle sentence about
copyright/permissions notice is not in the first), so I'm including a verbatim
copy-paste from http://www.kryogenix.org/code/browser/licence.html here:
