attached you find a diff to davresource to version 0.1.2

i use this version for a web client using mod_python, and i
needed the functionality so i implemented it myself

changes:

added move,copy,mtime methods
added a check keyword argument to DAVFile, so we do not need
to issue a request each time an instance is created wher we
already know that it is a collection or file

i want to release the web client under an os license but
don't want to include pydavclient in the distribution, so it
would be fine if there is some release of pydavclient with
this features
