Structures built of Multiple Blocks

Part of Druid's initial vision for the Engineer was building fortifications. I do not feel we have achieved that yet. Blocks are very difficult to place accurately.

I have been toying with the idea of having predefined structures built of a number of blocks, that can be summoned in one integral unit.
I have put the code in cvs for it, and updated the rpg.ini file accordingly.

The idea is that we have a separate artifact for each structure. You deploy the trans, activate the artifact, and it creates the structuce - using between 2 and 15 blocks, placing each block in the correct place.

In cvs are 6 such structures, of various shapes, using between 5 and 14 blocks. Let's have a play and see if we like the idea. Then someone can work out what the exact variety of structures available should be.
