v0.1.0-beta

This release mostly (see crates.io) consists mainly of polishing the many changes described in the 0.1.0-alpha release notes.

Other significant improvements include:

• New store_value() and StoredValue APIs that allow you to use the reactive system to store Copy and 'static handles to non-reactive values, just as you can with reactive signals.
• Finally, complete integration with the cargo-leptos build tool, including transitioning most of the examples over to use cargo-leptos (except for the client-only examples, which use Trunk) (kudos and many thanks to @benwis and @akesson)
• Restoring stable support for the new version (thanks to @jquesada2016)

... in addition to many small bug-fixes.

We're making very good progress toward a final 0.1.0 release. The only outstanding changes at this point involve improving and updating documentation, slightly loosening a couple APIs to make them easier to use (for example, allowing the path property on <Route/> to take T: impl std::fmt::Display rather than &'static str), and a few performance improvements (like optimized SSR) that will have absolutely no effect on the API exposed to users, but continue to ensure high performance and a good experience.
