Remove unneeded files...
Half fix weird flip of scene which always seems to be the case. This camera projection matrix stuff is wrong anyway, but at least this makes things better for the moment...
Forgotten files removing GLee.h includes from a previous commit.
Weird file encoding issues...
Hack attempt to get importing of quads working...
Added message box warning if Export button was pressed without "Birthing" Ivy to generate geometry first.
Changed OBJ export to explicitly indicate a new object for each different material grouping. This has the effect of exporting the different objects which have different materials as discrete groups which makes importing and material applying in 3D app easier.
Attempt to give compiler all the help it can get for optimisation...
Misc tweaks...
