fixed uKeys (aka almost revert it back)

ios: turn on more warning messages and start correcting them

memory leak in hwform.cpp (issue #386)

fix compiling hw for ios (was looking for the wrong math.h and used an old variable name)

Seems to me placing hogs does not need 5s since it is a fixed interval now. Maybe if placing hogs was ever 0 seconds or something.

Oops

Make pas2c even smarter. Now uIO.c compiles fine, and only 1 warning when compiled with -Wall (clang).

- Don't crash on back press, but shutdown hedgewars - enable volume up/down/mute buttons

- Added support for keyboards on android - tiny patch for android/sdl tracks backspace correctly now - Added SDL_SCANCODE_X constants in uKeys - First attempt at making the touch interface and keys input work side by side
