Changed Flag, Globals, and Mapwalk

Removed NavBar and Flag bitmaps, updated Book of Knowledge DTM and
srl_outline_black color.
Fixed rs_OnMinimap (requires new global bitmap bmpMinimapMask)
Absolutely final changes to the screen constants.  Should all be in
sensical positions.
In Bank.simba, updated the following to reflect the screen constant
changes:
* MSTPointToBankPoint
* BankPointToBankIndex
* BankIndexToBankPoint
* BankIndexToMSPoint
* BankIndexToMSBox

I may have broken other things based on the constants changes.  If so,
my apologies.
