hgweb: move entry-preparing code from webcommands to webutils.commonentry()

hgweb: move entry-preparing code from webcommands to webutils.commonentry()

The new function is used to fill basic information about a ctx, such as
revision number and hash, author, commit message, etc. Before, every webcommand
used to get this basic information on its own using some boilerplate code, and
some things in some places just weren't available.
