[Cosmo-dev] JS error-handling in the UI

[Matthew Eernisse]

Agreed 100%. And when we can implement something that doesn't prevent us 
from using normal debug tools when we're working on the app, I'll be 
behind that wholeheartedly.

I'll be happy to help in whatever way needed to implement something like 
that for all client-side errors -- the key being that it can be easily 
and permanently disabled in the dev environment (i.e., no local changes 
to files you have to worry about getting committed/overwritten with svn).
