janwas 953d2621dd timer: improved timer_add_client - no longer has fixed-size storage. btw, name will change here - not happy with SUM_TIMER.
GUI/input code: moved g_active, g_keys etc. into ps/Globals; it has its
own input handler as well

all users of fopen(): add file_make_full_native_path to get correct path
even though current dir = system/

This was SVN commit r2954.

/*
This module drives the game when running without Atlas (our integrated
map editor). It receives input and OS messages via SDL and feeds them
into the input dispatcher, where they are passed on to the game GUI and
simulation.
It also contains main(), which either runs the above controller or
that of Atlas depending on commandline parameters.
