Philips: Improved support for ChannelMap_xxx channel lists directory structure.

Browse Source 
Selecting any .xml or .bin file in the folder will now load all DVB\*.xml files from the
channellib and s2channellib sub folders.

The Loader can now return multiple file names to the MainForm that it will use for backup/restore.
