Begin reworking many internals to push for v0.1. 
- Beginning to transition View types to use Rc/RefCell internally,
  which should provide better guarantees about ownership on the Rust side.
  This is also important for certain Objective-C side scenarios where we
  may need to set an ivar after creation, which requires some level of
  mutability. This may also possibly help bring down the unsafe usage,
  which would be cool.

- Rewrote the Color module; this now handles system colors better, and
  provides support for dynamic color creation. Supporting combinations
  of dark/light/contrast is now possible with handler passed in via
  `Color::dynamic`. This still has work to do in terms of some accessor
  methods and such, but it works well for now. The `to_platform...`
  method should be removed before v0.1.

- Added a new feature for enabling fallback color usage on older macOS
  versions that don't support system colors. This may honestly never be
  used, but it cost nothing to implement.

- Fixed a bug in the Autolayout wrapper where dereferencing could cause
  constraints to crash at runtime.

- Support setting text color on labels.

- Support setting text color on buttons, albeit very hacky right now.
  This needs to be extracted and/or cleaned up, but getting it sketched
  out was important for this commit.

- Support setting a key equivalent on buttons.

- Creating a local event monitor is now possible.

- Examples updated; Calculator clone example added.

The only API breaking change in this commit from earlier commits should
be `color::rgb` needing to be `color::Color` followed by a
`Color::rgb(...)` call.

Tasks Example

This example implements a "full featured" macOS app, completely in Rust. Notably, it showcases the following:

  • Working menu(s), with dispatchable actions.
  • A cached, reusable ListView.
    • Cell configuration and styling.
    • Row actions: complete a task, mark a task as incomplete.
    • Basic animation support.
    • Self-sizing rows based on autolayout.
  • Custom widget composition (see preferences/toggle_option_view.rs.
  • Multiple windows.
  • Toolbars per-window.
  • Button and Toolbar Items, with actions.
  • Running a window as a modal sheet.
  • Autolayout to handle UI across the board.
  • Message dispatch (a bit jank, but hey, that's fine for now).
  • Standard "Preferences" screens
    • A general and advanced pane, with pane selection.
    • Looks correct on both Big Sur, as well as Catalina and earlier.

While the Cacao API is still subject to changes and revisions, this hopefully illustrates what's possible with everything as it currently exists, and provides an entry point for outside contributors to get their feet wet.
