I know this isn't my branch, but found several reference haemmoragers and figured it'd be appropriate to commit here.

<Alam_Squeeze> Makefile:770: recipe for target '../objs/Mingw/Debug/lua_blockmaplib.o' failed
<Alam_Squeeze> make: *** [../objs/Mingw/Debug/lua_blockmaplib.o] Error 1

This makes it less likely for the game to crash when stuff is used outside a level when they shouldn't be

my P_SearchBlockmap_* functions are now a single searchBlockmap function, you can choose between "objects" and "lines" with the first arg to decide what to iterate through. I also rearranged the argument order a bit for easy stack cleanup etc

I'll remove the old stuff later, don't worry, it's disabled for now
