Major overhaul of input and communication systems

* Add input manager

* WIP lifetime hell

* Hell yeah, dark lifetime magic

* Replace events with actions in tools

* Fix borrow in GlobalEventHandler

* Fix typo in response-handler

* Distribute dispatch structure

* Add translation from events to actions

* Port default key actions to input_mapper

* Split actions macro

* Add handling for Ambiguous Mouse events

* Fix warnings and clippy lints

* Add actions macro

* WIP rework

* Add AsMessage macro

* Add implementation for derived enums

* Add macro implementation for top level message

* Add #[child] attribute to indicate derivation

* Replace some mentions of Actions and Responses with Message

* It compiles !!!

* Add functionality to some message handlers

* Add document rendering

* ICE

* Rework the previous code while keeping basic functionality

* Reduce parent-top-level macro args to only two

* Add workaround for ICE

* Fix cyclic reference in document.rs

* Make derive_transitive_child a bit more powerful

This addresses the todo that was left,
enabling arbitrary expressions to be passed as the last
parameter of a #[parent] attribute

* Adapt frontend message format

* Make responses use VecDeque

Our responses are a queue so we should use a queue type for them

* Move traits to sensible location

* Are we rectangle yet?

* Simplify, improve & document `derive_discriminant`

* Change `child` to `sub_discriminant`

This only applies to `ToDiscriminant`.
Code using `#[impl_message]` continues to work.

* Add docs for `derive_transitive_child`

* Finish docs and improve macros

The improvements are that impl_message now uses trait
resolution to obtain the parent's discriminant
and that derive_as_message now allows for non-unit
variants (which we don't use but it's nice to have,
just in case)

* Remove logging call

* Move files around and cleanup structure

* Fix proc macro doc tests

* Improve actions_fn!() macro

* Add ellipse tool

* Pass populated actions list to the input mapper

* Add KeyState bitvector

* Merge mouse buttons into "keyboard"

* Add macro for initialization of key mapper table

* Add syntactic sugar for the macro

* Implement mapping function

* Translate the remaining tools

* Fix shape tool

* Add keybindings for line and pen tool

* Fix modifiers

* Cleanup

* Add doc comments for the actions macro

* Fix formatting

* Rename MouseMove to PointerMove

* Add keybinds for tools

* Apply review suggestions

* Rename KeyMappings -> KeyMappingEntries

* Apply review changes
