HG Fetch with username and password in url

We currently use an company internal mercurial server with username and 
password authentication
that will be accessed during the build of a firmware image from within a 
custom recipe.
The only way to access it from within the yocto toolchain seems to have 
the username and password
stored within the URL of the SRC_URI variable.

But the current hg.py fetcher does not completely support this. Attached 
is a patch that fixes the missing parts.
