[PATCH] Allow gitweb tab width to be set per project.

[Magnus Hagander <magnus@hagander.net>]

Allow the gitweb.tabwidth option to control how many spaces a tab
gets expanded to.

In the PostgreSQL project, we're using 4-space tabs, but we have other projects
as well on our gitweb server, so we need to be able to control this on a
per-project basis.
