Revive sage-test-mode

[nthiery]

With the old sage-mode, C-c C-t on a buffer was running sage -t on the corresponding file,
and the test log was rendered in a useful way, with clickable links to the failing doctests and so on.

Could this be revived in sage-shell-mode?

Thanks in advance!

+1 !

In the mean time, I've a workaround which allows a similar workflow: I'm abusing "M-x compile" pretending the compilation command is "sage -t foo.py". The errors are correctly parsed and generate clickable links.
