Add several more detectors

[h3ndrik]

This will add 3 more detector nodes:

• An inventory scanner that works like the ones at the airport. You can also list several itemstrings (separated by space or comma) and it will detect if the player has any of those in their posession. (Leave empty and it will detect if player has anything in her/his inventory
• An awards scanner: To be used with the awards mod. Will activate if player has unlocked specified awards.
• An playerfactions scanner: To be used with the playerfactions mod. Activates if player is member of specified faction.

I put them all into one mod, because the code is almost identical. (named 'moremesecons_detector' analogous to 'mesecons_detector' where i also borrowed the code structure)

Sorry i'm not good at making textures, so the textures are just borrowed from core mods. I'd be happy if someone else could paint some textures.
