UI: Correctly set 'shell/open/command; registry key for file associations (#5244)

Browse source 
* Correctly set 'shell/open/command; registry key for file associations

* File association fixes
* 'using' statements instead of blocks
* Idempotent unregistration
* Single "hey shell, we changed file associations" notification at the
  end instead of 1 for every operation, speeds things up greatly.

* Adapt and fix Linux specific function as well
