better error messages

[dcsan]

we often see these errors:

 boteditor-0 Unknown command '＋' at stream() line XXX

It would be great if the error had the topic, as the authors don't usually edit the whole file, just individual topics before everything is bundled together into one file for the interpreter.

also every single day we get triggers with capital I in them. It's just impossible to train writers to write in all lowercase. Any further thoughts on doing a .toLowerCase() on triggers?
I can't recall why you didnt want to do this, something related to UTF8?
is there a way I can do this to the engine and still maintain the ability to upgrade - perhaps as a feature flag? forceLowerCase=true like the utf8 flag.

Syntax error: Triggers can't contain uppercase letters, backslashes or dots in UTF-8 mode at stream() line 10316 near + how do I get to walnut creek?
