Travis speedup

Found the cause of your pytest failure: PyPy bundles an old and customised version of pytest

Awesome, many thanks!

Spoke too soon, from https://travis-ci.org/futurecore/revelation/builds/73694067

The command "python -m doctest scripts/diff_trace.py" exited with 0.
0.35s$ test "$TRANSLATE" == "true" && ${HOME}/pypy/rpython/bin/rpython --opt=jit epiphany/sim.py || true

The translation isn't so important at the moment. I'll ask the pypy people how they deal with this stuff in their own repos. Maybe they don't install py.test from pip.

[moreati]

Okay, note that Travis install pytest themselves and pytest requires py - so you get some version regardless of pip or PyPy

[snim2]

Good point.

[moreati]

There's https://pypi.python.org/pypi/rpython/ - nothing bundled, depends on pytest, last release Apr 2015. However it does say

Warning
This is an experimental release of a randomly chosen, untested version of RPython. Packaging issues are likely, feedback is welcome.
