Consider using Mercurial's config parser instead of ConfigParser

[sheep]

Currently Hatta uses ConfigParser for parsing its configuration files (which are roughly in .ini format). That module is included in Python's standard library.

But Mercurial (required by Hatta) also has a config file reader (and also using roughly .ini format). It's much simpler than than ConfigParser, but doesn't have its limitations about requiring sections.

It may be worthwhile to use the Mercurial's library.

One thing that hg's parser lacks is saving, which is used by HattaQTIcon.
