Title: Some improvements to the GP editor

- now the GPs are classified by group, just like tracks: standard, user defined and add-ons
- allow empty GPs to be loaded by the GP manager, so that they can appear
on the GP editor (but not on the track selection screen)
- enable/disable buttons on the main screen depending on the selected GP
- some minor bug corrections
