Changed the querymap structure... it's now got an underlying multimap
with 2^n keys for any entity with n components... not sure if the faster
lookup time is really worth the much slower write time.
Added an awesome variadic template for creating nodes much more simply.
Added a camera component and system... getting ready to actually start
rendering stuff. Yipee. Sure is taking long enough.
Found a stupid core glitch... TerminalEntity is being added to the
SpritesNode :(
Fixed the core issue. Got textures loading... not quite drawing yet
though
Finally, rendering kinda works. In a stupid way though. Mipmaps were the
problem. sigh.
Hooray. Controlled cameras kinda work now.
