Migrate to bevy 0.10

[Fincap]

Hi all,

I've tried my hand at migrating this plugin to be compatible with the new Bevy 0.10 version. This is forked from the main branch and not the beta branch, with the intent of getting a working version of this plugin released ASAP.

This is currently in draft phase, as there are a couple outstanding issues. While the changes committed will compile fine, functionality when executing the examples is broken. I am creating this pull request now to seek assistance with fixing this issue before finalising.

I will leave annotations describing the issues requiring resolution. Any and all responses are appreciated :)

Additionally, given the issues get resolved, should a commit be made to bump the version of the plugin to something like 0.11.1 as a "bridge" version that is compatible with the latest bevy version and is available to be used while the beta refactor is still undergoing completion?

Thanks for your fix @soerenmeier :) Once aevyrie/bevy_mod_raycast#72 is approved, I will update the cargo file and take this PR out of draft mode.

I realised that removing many of the PickingSystem variants, while not impacting the library or examples, may inadvertently break module user's reliance on the labels of particular systems.

A result of this is that each plugin's systems are now individually labelled in PickingSystem, however three additional sets have been created (PickingSet, InteractableSet, and CustomHighlightSet) which represent the three "groups" of systems. They are used in the library to order each system and apply run conditions. Alternatively, these three variants can be removed and a distributive_run_if can be applied to the systems tuple, but that means that each system in the set is individually queried for its run condition each loop rather than one for the system set as a whole.

Any news about the upgrade?

Any news about the upgrade?

I am still waiting for bevy_mod_raycast to be updated to 0.10 before moving this PR out of draft.

In the meantime, if you'd like to use this branch in your project you can update your Cargo.toml to include:
bevy_mod_picking = {git = "https://github.com/Fincap/bevy_mod_picking", branch = "migrate-bevy-0.10.0"}

Thank you works fine 👍
