Added in code to allow an INI-style file to override the channel number. Checks channel name (if present) and uses it to rewrite a given channel number. A generic overwrite can be overwritten with a device specific one.
Idea is to have less mass editing of channel numbers iwhtin DigiGuide listings. Means that people could automate the generation of the file or even share between users.
Want to do some more work on it though - to make sure that multi-device handling works well enough.
