- Fixed an issue with types not stacking

- Quick update to ensure block in a conveyor system is functional before counting as a connection.

- Fixed issue with sorting not following conveyor system. Now blocks must be attached for their inventory to move between one another. This makes sorting completely legitimate now. (No more magical sorting between unconnected blocks)
- Added [Exempt] tag which means the block will be exempt from having it's inventory pulled
- Added refineries, assemblers and connectors as valid targets for pulling inventory from. You can not pull inventory INTO assemblers, refineries or connectors YET, but I did this to try to curb push / pull situations. (Where inventory bounces back and forth). So that means you can only pull OUT OF them for now. You can now pull items out of assemblers and refineries after they are created (good for moving ore that's been refined, or items that are building at assemblers).
- Fixed issues with case sensivity

- Initial Release
