Document that WebDAV doesn't need git on the server, and works over SSL
I managed to set up a Git repository on a preconfigured WebDAV server,
and using HTTPS, without installing Git on it or changing the server
configuration. This works through a proxy too. This patch reflects
this (it previously stated that Git was _necessary_ on the server,
which isn't true). Also give a few hints to troubleshoting.
