Travis config to run on all branches except master.

I think if this is set and we keep the number of branches low, anyone else will have travis automatically ready to run against their forks. They'll just have to enable the github travis service hook and it will be pre-configured.

Backwards compatibility fix for RecordSensor region
build: update configure (unix) to accpept python 2.7 too

both python version 2.6, 2.7 are supported, there's little difference:
http://docs.python.org/dev/whatsnew/2.7.html#porting-to-python-2-7
enable python 2.6 / 2.7 in include header files

conditional include on _PY27 defined in configure if python is v2.7
make links for python2.7 -> python2.6 in external/ dir

this enables build with python2.7
not necessary after libs are modular
