Hungarian locale

updated lua loading in the ifrontend and also fixed masked maps

Engine/Frontend: * Changed the Lua file loading to take paths relative to the data dir instead of absolute paths to ensure demo/savegame portability

Update translations, add a hungarian stub for edge_hog who is volunteering

playing a bit with colors

implemented endless turns support and added Timeless scheme (also fixed a crasher) new save button from Tiy other minor stuff

Correct bug in flight ceiling for birdy as well, increase clip on velocity to 1.9 (shouldn't cause problems with most collision checks still), apply clip to both + and -

Engine: * Write log files to different files in a new sub directory depending on "game mode"

merge

have engine try for a second position when map loading fails (in this way it's possible to move Missions data to any path) remove nsstringextra and implement raw dump when needed

further rework of MapConfigViewController, lists missions correctly (they don't load fine yet)

move all preview drawing code into its own class (for a simplified and more readable MapConfigViewController)

remove windspeed from bubbles, remove initial dY from bubbles, apply dY/dX to bubbles, correct offsets on flying saucer flame graphics, add bubbles when flying saucer thrusts underwater, make flying saucer sink more slowly underwater

Can't use cHealthDecrease here for these two 'cause it isn't a generic "do some damage to hog" flag, but is rather set when SD starts

Allow UFO to go underwater. Keep UFO active if it runs out of fuel in the air/water, just disable controls.
