use constant for tile size in the renderer texture loader

disable some cramping box2d debug renderer flags by default
begin implementing a query callback (for AABB tests and such).
implement tile physics body destruction via AABB queries

position is a bit screwy though.
make AABB tiel destruction query more precise..something is off still though
trying to use a aabb query to destroy a tile..it's a bit closer

but it retursn more than one body (on average, 4). i don't get how though
because how is it possible that TestPoint is returning true for those?
Doesn't make sense..surely they can't all be contained in them?
set tile removal origin (phys body) at center of the tile we want to

remove, otherwise it gets all 4. tile breakign works great now, destroying
the physics just fine
be sure to delete tile body user data
reinstate block picking radius caps, but only if we're not in debug mode

since i kind of need this for testing.
when we destroy the physics tile, cast userdata to the right ptr and delete
fix the quickbar gui size so it looks better
make chatbar less horrendously huge
fix vertical titlebar alignment so it doesn't look so dang bad
tone down the bright red titlebar, bugging me too much even thought it's

all just placeholder art.
make zoom and mouse wheel (inv. switching) require no gui input to be

listening..otherwise you could do this stuff when you were in the main
menu and what not.
