(svn r1799) -Codechange: [ Multistop ] Added debug class "ms" and more debugging
output for multistops

(svn r1798) GetFoo(i)->index is per definition i, so replace the former with the latter

(svn r1797) Clean up TileLoopClearHelper() a bit:
- if cascades -> switch
- uint -> TileIndex
- (uint)-1 -> INVALID_TILE
- don't treat non-flags as flags

(svn r1796) Revert r1792, because MorphOS has defaults for CC/CXX, they're just wrong, so setting CC/CXX using ?= simply did nothing

(svn r1795) Change CFLAGS for MorphOS (tokai)

(svn r1794) Make the dedicated server compile again under MorphOS (tokai)

(svn r1793) Revert one instance of $(shell) back to ``, because MorphOS does The Wrong Thing(tm) when date is used within $(shell)

(svn r1792) Revert r1761 and set fallback values via ?= for CC and CXX as there seem to be platforms (MorphOS) out there which don't provide some proper defaults.
Use gcc and g++ as defaults, because cc and c++ aren't available either. *sigh*

(svn r1791) Remove the remnants of CMD_DESTROY_INDUSTRY, which was removed a long time ago

(svn r1790) Make CmdPlantTree() and related functions more safe and (hopefully) more readable:
- check if end tile is on the map
- uint -> TileIndex
- if cascades -> switch
