Prevent crasher if attempting to show ammo menu

new menupage ingame for common actions new style for moving the main menu

General: * Removed FindLua51 cmake module as fpc does it's own lookup anyway

allow to compile engine as library with HWLIBRARY symbol move the first run check in the first view controller instead of appdelegate relocate things around to make room for controls/buttons/menu

Engine: * Added alt weapon icon to parachute and flying saucer * Hide alt weapon icon once weapon was used

Engine: * Show alternative weapon that might be used while on rope (if any is selected)

Engine: * Added executable icon (Win32 only) * Added window icon * Tiy should redo both as I couldn't get them right (blurred/transparency)

add a new way to fetch version info from pascal to c complete the stubs for the new lua section fixed a glitch in the ifrontend

Engine: * Excluded Lua scripting on iPhone Frontend: * Some stylesheet tweaks by Tiy and me

Engine: * Redirect debug log to stderr in case no path was provided (e.g. run from command line)

Engine: * Proper cleanup after creating landscape preview * Avoid trying to write to current working directory (no-go under Windows Vista/7 if installed to C:\Program Files)

Engine: * Last pointer cast removed (I hope)

Engine: * Forgot another gear pointer -> gear uid change

Engine: * Prevent script calls with no script loaded (error spam)

Engine: * Submit gear UID to script functions instead of gear pointer on gear add/delete
