Add ability to sell back a resource for CP.

Add the ability to sell back a resource for the CP it cost.

This will need the following considerations:

• Was within a reasonable time limit (2~3 minutes)
• Is not damaged in a major way... see this
• Was purchased by the selling player see this

Selling captured transport should also be an option, IMHO.

I think I'm going to give this a go next but I want to run something by you guys. I have 2 ideas of how to do this. We can do this in a very simple way, as in you select the option from the officer/FOB, you get in the vehicle you wish to sell back, it gives you an action that allows it to be sold, and presto. Or we can do it in a fancy way with a GUI. I was thinking it could be the classic 2 pane window with a list of vehicles on the left, you can select multiple to move to the right pane, hit "Sell", and you just sold multiple vehicles at once. However, I have no idea how to make a GUI so I'll need some help with that.

Other than that, I think vehicle damage should really focus on the engine state and wheels/treads. Obviously we can expand this to get real nit picky but that can come later. What do you guys think?

@bolbies Either is fine by me. I like the GUI idea. I honestly don't really know much about building GUIs from scratch with the ArmA tools. Honestly, what I have been doing is manually editing an existing screen then copying the source from the git hub folder I have on my PC to the My Documents folder for ArmA and playing the game there to make sure the screen look and works okay after my edits. It's terribly inefficient but it works.
