ZBefunge v0.7 beta known bugs
-----------------------------

Arithemetic problems with:
--------------------------
rand32b.bf
rand64b.bf
sinus.bf

UI Problem
----------
dladv.bf/drx.bf conflict.  Should ~ wait till you press enter before
carrying on, as in Chris Pressey's C code?  This seems a bit silly.  But
these two programs (and others) behave strangely otherwise (I echo the 
character you press, as soon as you press it).

Fix compiler warnings.
Tidy up source code, put in more logical modules.
