Added Travis CI file, integration test (#135)

* Added travis CI file

* Testing travis in C mode but running a python test.

* hopefully this build doesn't stay perpetually queued.

* Checking whether I can add distributions without doing a matrix.

* running another shell script

* Added an integration test script. Will need some tweaking to get it working properly, but it should run in the travis build without affecting the status. Current expected output is 'NRPE: Unable to read output.'

* Forgot to add execute to test-wrapper.

* sudo on test wrapper

* Making sure nrpe.cfg looks right on travis build.

* changed directory of new plugin to one that user 'nagios' has access to.

* Checking directory of script before certain operations

* Making sure we give correct cd instructions.

* checking directory structure for travis/ubuntu/whatever

* Trying again.

* Added execute permissions to plugin

* Test is now passing. Test wrapper now requires travis-test-1 to pass.

* Somehow we can't find the test script now

* Build should actually pass this time.
