LuaDevice now works fully, without any weird bugs. Yay!
This took quite a bit of bugstomping to arrive to; some of which ended up discovering I'm not particularly proud of doing. Oops!
The LuaCpu implementation no longer has a UART implementation in C++ (which actually leaked everytime a LuaCpu was garbage collected... Yeesh) - instead the Lua entity code actually implements the UART! Pretty cool to see the fruits of my labor actually working!
The LuaHelpers macros are renamed slightly to make them less of a pain (and also because I think having `_IMPLEMENT` in a function implementation is a bit stupid.)
I have updated the ideas document to better reflect my plans for the project system.
