Handle errors in a sensible way

Currently we hook directly into util functions and bring error handling code there. This is real bad™, and it'd be preferable to have them in the apis themselves.

Additionally, it'd be nice to have an easy way to file bugs, so provide a compile time environment variable for bug reports and show an additional ui for it when a syncronous error occurs
