UI improvement - keep property focus

[RadekPilich]

When switching between Turn and Push configs, the active property (Chan, Numb...) changes somehow. I suggest it would be nicer if either:

1. The same property would be active - i.e Chan active on Turn, after switching to Push, Chan is active, change active to Numb, after switching back to Turn, Numb is active
2. Turn and Push will remember it's last active property - i.e Chan active on Turn, after switching to Push, Numb is active from before, change active to Low, after switching back to Turn, Chan is active as before

Regardless of the above, there is an issue at the moment, where value boxes under encoders don't refresh correctly when switching between Turn and Push configs, which can sometimes lead to confusion, especially for properties present on both Turn and Push configs.

Similar (or possibly in contrast) to the above, setups should remember the last active group. That would make it much easier to copy individual encoders between groups in different setups.
