Add support for extension modules
This adds support for an [extensions] section to hgrc. This has the form of:
[extensions]
mod=[path]
If a path is specified, the python module found at that path is load.
Otherwise, __import__ is used to find the module.
Each module must implement a dict called cmdtable where the command line
options for that module live. Each module must also implement a reposetup
function:
cmdtable = {}
def reposetup(ui, repo): pass
Index: hg/mercurial/ui.py
