ConfHandler.py: Add a hook for config parsing
To make the UI settings take effect, we need to hook at the end of each config file parsing and set UI specific values.

74# We have an issue where a UI might want to enforce particular settings such as
75# an empty DISTRO variable. If configuration files do something like assigning
76# a weak default, it turns out to be very difficult to filter out these changes,
77# particularly when the weak default might appear half way though parsing a chain
78# of configuration files. We therefore let the UIs hook into configuration file
79# parsing. This turns out to be a hard problem to solve any other way.
