add new panic() method, though not yet used. revert to java target if cannot find specified target
Big change to error messages themselves by removing single quotes for non input text stuff.  Made cannot_find_tokens_file more specific (split it). Added offending token information to a lot of the messages.  It now only prints the file name and not the full path to the file in error messages. Re-factored the ANTLRMessage hierarchy to share fields. Getting the offending token required number of methods to take different arguments. removed the default ST listener in the error manager as it is apparently unused.  Cannot find imported grammar is now a grammar error not a tool error.
use assoc value's token.
Add convenience methods for detecting missing targets. At a few bail out points so that we don't try anything that will need code generator if we get an improper target.
put good quotes back in. rm unneeded arg to left-recur msg.
move templatesExist to Target

I messed up the merge a bit in ErrorType. Made something into a grammar error not tool error. changed tool error back so it does not accept a token in the grammar.
