Improve context menu action configs and UX

[mharis001]

When merged this pull request will:

• Cleanup and improve context_actions component
  • Improve loadout/inventory/vehicle appearance actions UX by adding a "Edit" sub-action but keeping main action as a shortcut, Close Improve Loadout Editing UX in a unit’s context menu #151
  • Move code from config to separate functions - most are very short but I think it is better than keeping in config
  • Add combat mode action (also improve other group property action conditions to exclude player only groups)
  • Add icons for actions that didn't previously have them
  • Move remote control action to context_actions component
  • Cleanup priority entry usage, requires CBA_fnc_sortNestedArray - Preserve order of elements with same sorting value CBATeam/CBA_A3#1271
• Improve right-click context menu opening condition check - allow opening if groups of sideLogic are selected
• Simplify context menu local scope variable names, allow _args to be defined in config

I definitely like that the config code has been moved into separate functions, makes it far more readable and reduces code floating around.
