Enabled all of the WebDAV method names for use by third-party

modules, Limit, and Script directives.  That includes PATCH,
PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.
Improved mod_actions.c so that it can use any of the methods
defined in httpd.h.  Added ap_method_number_of(method) for
getting the internal method number.

I would have preferred to use a configurable table for new methods,
but the current API is too dependent on methods being represented as
a bitmask.  We need to rethink this in the next major server version.
