Title: More helpful error messages

Fixes/helps with [issue 3570](https://code.google.com/p/sympy/issues/detail?id=3570).

Changes:

- Exceptions during evaluation that are not caught (i.e. exceptions that occur in the Live code and not the user code) are sent back
- Error handler displays the proper error message now (timeout/HTTP error message)
