I don't think we will need a DB here, just simply call gitstats() recusively.

Remove gnu plot

On systems like Arch Linux `python` defaults to `python3` preventing
gitstats to start. This fixes it.

[hoxu@users.sf.net: Debian Jessie and CentOS 6.5 have /usr/bin/python2,
but OS X Yosemite only has /usr/bin/python2.7. There does not seem to be
a portable way to refer to python 2.x, so unfortunately on some
platforms the shebang needs to be modified manually]

When generating HTML output with a custom stylesheet specified using
-c style='mystyle.css' the CSS file specified was not being copied to
the target directory.

Split limit 5 was off by one, which resulted in incorrect
processing of file paths with spaces embedded in them.
New split limit of 4 gets the required parts, because it
specifies the allowed number of splits, not elements:

mode type hash size name
    1    2    3    4

This is really useful when computing statistics over a set of
repositories, where some repositories are much older than other.

This fixes a memory / ressource leak that manifests when computing
stats over big sets of repositories. It was eating more than 8G of
memory for ~15 git repositories.

The code already checks for python 2.6.

Without this, author names containing `touch /tmp/vulnerable` would cause said
file to appear after generating statistics for the given repository.

This is not an optimal solution. Instead of blacklisting characters we should
either whitelist some, or find a safe escape mechanism for gnuplot.

* author.txt was renamed to AUTHOR
* use git shortlog instead of git-shortlog
  because the latter is not necessarily in PATH
