Mods can now have their own lua files.

Furthermore, added game.dofile function, which executes a lua file from the current mod directory.
Fixed unused parameter warnings.
Added tiered solar panels.
solar v1 (the normal one) generates 111 power (nerfed back from my previous upgrade). Available in reinforced version  (111 power)
solar v2 generates 222 power. Available in reinforced version (200) both as a rare recipe found in the robots for fun and profit book.
solar v3, the quantum solar panel. Found in the item lab ends.

Solar panels drop solar cells when they are damaged by Z's in the ame.

Fixed some of the badly placed items in the item lab ends.
Reduced solar cell weight by half. only half a kg now. So solar panels are not likely to dissasemble into more weight.
