New Feature: static fortifications can now be built by mercs (by Flugente)

- if the terrain allows it, an empty sandbag (item 1540) can be filled to a full sandbag (item 1541). You need to have a shovel (item 1015) in your second hand. You will notice the new hammer cursor
- by using a full sandbag, you can build a sandbag barrier
- by using a concertina stack, you can build a concertina wire barrier
- this only works if the current map has sandbags/concertina wire in its tileset
- with a shovel in your hand, you can remove a sandbag barrier
- changed the size of shovel so it can actually be put in inventories. It was also necessary to remove its ability to be used as a melee weapon.
