make runtime quality check for iDevices

land arrays are allocated dynamically, so DOWNSCALE and LOWRES macros are now removed and replaced by run time flags rqBlurryLand and rqLowRes

interpret parameters before initializing everything make flake disabling really works code cleanup and fixes

small cleanup

Minor fire tweak for readability and lethalness, remove exit condition that was hanging game (identified by jaylittle)

Revert prior attempted optimisation. Gridding the land pays in some situations, but not all. Restricting to an upper bound might help, but overall, seems too fuzzy to be worth it. On one side is increased cost of Add/Delete + extra test on collision check, on the other is skipping the list iteration. Perhaps for large lists.

Initialise to 0

Rename city to earthrise, replace old "earthrise" music w/ new City music on City/Planes

New music for City theme

New Rock themed music for Stage by HSR

Grid the landscape, and shortcircuit checks on the collision array if there are no nearby checked in collisions to be collided with. This is a big win for fire's ammoshove in particular. Also add a +2 that seemed missing in the check, and update fire accordingly.

Restore prior optimisation with the wildly out-of-bounds tx in LandDirty removed

Revert most of optimisation except for some obvious fixes to errors someone or other introduced. Something in the rest appears related to a crash in translation. Until I determine why or what, this stays out to not ruin people's games
