New feature (by DepressivesBrot): Molle Items

- individual LBE gear can be created via MOLLE items. For each LBE item, there's a definition which pockets may be changed and how much space the new pockets may take up in total.
- If there's a free pocket slot and enough space -> attach item and enable pocket.
- for further description, see Doc/Design Document- MOLLE.txt
