First version of SEM HFW and magnification coupling
HFW trackig bug fix
Fixed merge conflict
acq test: clean up
Merge remote-tracking branch 'remotes/origin/sem_magnification'
gui canvas: simplify magnification handling

only do it on the SEM view
only do it if there is a horizontalFoV VA
gui model: clean up
gui/odemisd: detect and display remote exceptions

handy to know what actually caused the problem remotely.
Idea of the code based on Pyro4.util.getPyroTraceback()
