Added TOKEN_SKIP_* macros to tokenize.h.

Browse Source 
Changed error reporting during input port detokenization to fill a buffer
rather than fatalerror-ing immediately. Should now properly skip over
any invalid tokens.

Enhanced error detection during input port detokenization to catch 
duplicate bits. There are a lot of these!

Updated initialization code to print errors and fatal only if the input
ports were unable to be constructed at all.
