Main Mod Directory Change for Lua Global Value,  someother things

Normally I would commit this out separately, but considering the amount
of files...

Stonehearth uses your mods folder directory name to create a global
table for your mod. colors-base was unable to be created. colors_base is
accessible.

server_init now uses this instead of junking up _radiant.

replace_proxy_with_item_action looks to be depredicated now,
place_carrying_on_structure_adjacent_action seems to be the replacement.
I've updated to match this.
