Improve display of DOLFIN error messages #8
Description
Currently FEniCS bot answers on a failing solve with:
.@attmcrae: I failed to solve your problem...

According to Anders Logg, error messages are usually < 140 chars. Hence, we should grep for "Error:", "Reason:" and tweet the concatenation of both.
To reproduce this issue, here is a failing example is
Solve Poisson with f=13*pi*pi*sin(3*pi*x)*sin(2*pi*y) and tolerance=1e-8
(I dont actully understand why it fails because I don't see the error message).
