Cons now allocates String objects when outputting string form. Added
...
support for begin expressions and tweaked the GC to be more aggressive.

Added runtime error checking and line number tracking. Seems to catch most
...
Scheme program errors without making Rua abort now, although there are a
few things that still need to actually report errors instead of failing
in weird ways.

Bug fixes, plus a first stab at the garbage collector. It *seems* to work
...
properly so far.
