Sort out tests

[nicklasb]

The current testing is much a function of the networking and multihost aspect of the projects, where tests simply cannot be standalone and not take ages to complete.

However, some of the test can be run in normal manner, should therefore move into a normal pipeline.

Todo:

• Decide what tests go where (begin with those that run on Native)
• Create an appropriate pipeline
• Move unit-testable stuff into a that pipeline
• Decide on WTH should be done with the complex multihost stuff
