Implementation of non QML launcher

[iLLiCiTiT]

Changes

• Added new tool "launcher" to pype.tools which is not QML base
  • based on BigRoy's launcher draft
• Launcher's context is out of avalon.io.Session so we don't have to care about unexpected context changes
• Launching of application should be the same as from Ftrack (except triggering timer)
  • extracted launch_application function from ftrack to pype.lib

TODOs

• Action launch error handling
• Trigger timer on app launch

🏴	this depends on
pype-config	ynput/pype-config#75
avalon-core	ynput/avalon-core#177

Note

I think we can remove avalon-launcher repo.

Works well.

Small comments we discussed.

1. The button on the bottom right crashes the launcher.
2. Grouping of applications should be a bit more dynamic to to prevent group from showing if only one group member is available on the project.

Nice to see this being adopted by pype. Hope it's usable on your end. :) Any clients using this?
