Working on inventory. Made it so that items are hidden in boxes.

I am working on the inventory. It is taking shape.
I made it so that when you put items on the map, they can go into boxes.
tried to fixed something...
update
Merge branch 'inventory' of https://github.com/jensenr30/De_Flux into inventory

Conflicts:
	.gitignore
Added the guide doxc for maps and tile/item sets. Also added an idea from JP to the "ideas and plans" document.
changed "msp" to "psp". the stack pointer is for portals, so it makes sense to call it the "portal stack pointer" instead of the "map stack pointer". I have no idea what the fuck I was thinking calling it "msp".
^guid .doxc file. + enemies folder. ~reference folder
added more to the De_Flux Guide. Also changed a few minor things in the code.
proof read the "De_Flux core material.docx"

I put the finishing touches on the document.
It is now ready for consumption.
