Inventory tabs changes

1. Replace full tab names with single letters. This way inventory tab won't be forced to be so huge.
2. Make items in private tab not appear in tool dealers while selling items. It'll be nice place to hide your valuable stuff when selling lot of shit stuff.

+1 agree

For your first suggestion, that might be possible via skins.

 

As for the second, nothing in that tab is supposed to apear in selling screen to begin with, will look into it.
