gui: start of sparc acquisition manager
wip
Merge branch 'master' of delmic-server.local:odemis
gui: small refactoring and view focussing bug fix
gui: Added SEM stream that is activated on Sparc GUI launch
util: revert changes to getfluodb for it to work normally

the changes were only for testing, and never supposed to be committed.
gui: more work towards getting acquisition working for sparc
Merge branch 'master' of vpn.delmic.com:odemis
gui: add MicroscopeGUI.acquisitionView to list all the streams to acquire in the SPARC

This allows to add/remove streams to indicate which microscope needs to be acquired and
simplify the acquisition controller.

also simplify .views back to a simple list
