CI testing for the module

[ElectricMaxxx]

As a developer, i want to test this module inside an OXID eshop on travis.

AC's:

• a travis.yml exists -- got a script section to prepare the shop -- activates the module in the shop -- runs the tests of the module

Need to get some input by some other oxid devs:
