ditch unused renderbuffer in tilerenderer. textures are faster anyways
rm unused renderbuffer from lightrenderer, again. copy paste i guess
implement hotbarmodel properly (wip still)
silence nvidia khr_debug warning spam about mipmaps
bind to hotbar model
hotbar model works to provide data to view..works well so far

lots of issues ironed out, too. including no longer using context property
but letting qml make the object and retrieving the pointer from the type
system

for some reason model doesn't want to update on same-thread though.
it's identical to chatmodel except chatmodel isn't an actual abstractlistmodel,
but a signal/slot call immediately after hotbarmodel::reloaddata()
fixes all of this. (it was only loading things when you would move the view)
