MapModel: comments/docs, small tweaks

reimplement the quit engine+frontend keys

add ammoprop to enable to up and down buttons on for the touch interface

decouple current theme from map theme (fixes theme confusion bugs of last commit)

MapModel converted to QStandardItemList; separators fixed; changed used data format (human-readable struct instead of magic list) for map info in HwMapContainer (+ various small cleanups in that class)

MapModel, various cleanups. TODO/FIXME: QComboBox separator not working with custom models

messing with the theme model a bit (gets now auto-updated after DLC download too)

theme tweaks

Show number of points in drawn map

Cursor for DrawMapScene. Feel free to ajust its look.

mapContainer: use DataManager, reload maps after data update (e.g. by DLC)

make DLC trigger data reload

make DataManager a QObject with reload() slot that emits signal updated()

renaming HWDataManager -> DataManager

reimplement auto-kick for ignored players (it was temporarily removed during refactoring)

nemo said I was boring for removing the "hello" randomizer on room join. That was actually an accident, fixed by this commit. Now find an actual reason to call me boring (there are many to choose from :P) nemo!

Oh, and I guess this is needed as well, although if many other places in the code do this, pas2c will need to be a bit smarter and automatically wrap.

Make adler32 friendlier for pas2c - this should work the same (needs testing ofc)

Fix GetAmmoEntry in PascalExports

Get rid of overloaded functions in uAmmo

uCommands compiles

Fix types

Don't add duplicates into string consts

this should enable png screenshots on osx as well

in uTouch dont use bools to represent keystrokes, but issue ParseCommands

fix the ammomenu F# buttons

- change uKeys to be event based rather than polling - missing engine+frontend exit - missing controller support - needs testing on different platforms and keyboards

case sensitivity + correct variable check
