Interaction refactoring and replication

Initial refactoring of the interaction system to better lay the groundwork for interaction replication. Very rough untested draft as of now, changes include:

• Action/Hover now inherit from a BaseBehaviour which can save shared information, and adds some basic replication properties.
• Adds a BaseInteractionComponent which similarly to the BaseBehaviour contains replication and some general properties shared by both direct and ray interactors.
• Start/End functions have been condensed into one, and an Enum now separates the two. This reduces code duplication especially for replication by a lot.
• Adjusts other components such as intenselect to the new refactoring
• Callback for Behaviours that only executes on the originating client
• GrabBehaviour adjusted to replicate correctly

Missing changes:

• Test the whole thing:
  • Standalone seems to work fine
  • Dedicated server grab
  • Direct Interaction for
    • VR Grab
    • Grab seems to work fine for desktop Listen server + 2 clients
    • Cave Grav
    • Desktop + VR + Cave + Dedicated server Grab
  • Raycast Interaction for
    • Desktop Grab
    • Cave Grab
    • VR Grab
    • Desktop + VR + Cave + Dedicated server Grab
• Documentation and comments, especially the replication part
• Adjust blueprints and any other uassets
• Actually consider the replication process and add some more callbacks and events that can be used
• Naming scheme is wild
• Does it even make sense like this? This is just one possible approach
