Some nanotec testing at BOA and Oxford temperature controllers

I tested the nanotec a little at BOA. Not finished yet, especially the homing bit.

I also added support for an Oxfolrd Mercury temperature controller. But this is not
working because my simulation for the Mercury is a different version then the one
the EPICS driver is for.
