Changelog :

- new stylesheet created for overlay label
- since FDEV have renamed quite a few keys (e.g. 'Faction' to 'SystemFaction') in 2.0.02's Player Journal json files, in the bloody LIVE GAME!, take this into account - older logs will still be readable with the old keys, so imports will still work.
- Overlay widget colors now use the user-configured colours (except for white material percentage)
- tweaked the icon creation for the planet table icons
- use a normal label widget for the overlay Odometer and Distance to Sol, instead of the LCD widget
- planet table should now be sorted in natural order, for systems with more than 9/10 planets robiting one star
- Distance from Sol now reads to two decimal places, like the Odometer already was
- make sure an internal variable was being set to the current system name, at the appropriate time (i.e. right after an FSDJump)
- stop the Odometer value updating whilst loading the database - all those GUI updates kinda slow the loading down. It will display the Odoemeter value after the jump table loads
- Version bumped to 2.0.0 Beta 6
