The light calculation requires the random generator to be seeded with a
constant - otherwise repeated light recalculations would make the lights
change.
This patch allows the random generator to go back to the state before the
static seed().
- fix possible crash in conc (but it's still an ugly hack)
- fix noob usage of strcmp
- flag some memory leaks (it would be nice, if the author(s) would clean
up the mess himself)
- fix crash in substr
- whitespace cleanup
there are plenty more memory leaks in command.cpp - for example, every
goto in cubescript does not clean up anything
the printf format "llx" can not be used on all platforms (for example,
mingw uses a different name for it)
this patch provides a function, that manually converts a 64-bit integer
to a hex string
