Update to Bevy 0.13

[bushrat011899]

Objective

• Fix Update to Bevy 0.13 #105

Solution

• Bumped Bevy version to 0.13
• Updated Input references to ButtonInput
• Updated KeyCode values to prepend Key (e.g., KeyCode::W -> KeyCode::KeyW)
• Replaced Cube and Plane meshes with their new math primitives as recommended for depreciation reasons
• Explicitly converted Color into a StandardMaterial rather than relying on implicit into()
• Updated AddRollbackCommandExtension to match new lifetime generics for EntityCommands
• Implemented EntityMapper (which is now a trait instead of a type) for RollbackEntityMap, which will return the provided entity if it is not contained in the mapping. This ensures entities which are not tracked by the rollback map are not modified.
• Replaced the inner HashMap of the RollbackEntityMap with an EntityHashMap, which is an optimised type provided by Bevy.
• Updated the Component and Resource entity mapper plugins to use the new EntityMapper implementation provided by RollbackEntityMap. This removes a significant TODO on their implementations where if a mapping was done over a non-rollback entity, the mapping had to be undone.
• Ran fmt and clippy and ensured clean output.

Tests and the synctest example work as expected. I haven't had a chance to verify this against a real multiplayer application, so if anyone has the free time to test this branch out, please do!

Looks great to me!

Nice to see so many red lines 🧹

I haven't tested in any of my projects. Still lagging a bit behind and haven't even finished the 0.12 migration for cargo space.

I have enough time, I'll check with extreme bevy tomorrow. Otherwise, I think we should just go ahead. If anything shows up later we could always do a patch release.

Tested with matchbox and extreme_bevy now. Everything works like a charm :)

Okay, we just need to fix the conflict, then we can merge this :)
