Store known but uncompiled nodes in the symbol table

Browse source 
- Don't bother keeping track of uncompiled nodes in a special table. Use
  the regular symbol table instead. This should in the future make
  compiling nodes referenced deeper than (and before) their definitions
  fairly straightforward.
- Also, break up the compiler's Message() function into Warn() and Error()
  and get rid of zcc_errors.h. I can't really see having a set of error
  numbers being useful.
