Only build once with 2.7 on Travis.

Saving some more time on CI, and checking that the docs build with old
numpys as well.

Some examples needed to be fixed to build on python2.7+numpy1.7.

Delete examples/misc/rec_join_demo.py which is not working on numpy
1.7.1 -- not fixing it, as rec_join is arguably better provided by
pandas-style librairies anyways.
