WASM Support (the sequel)

v0.8.183 was great but I made a mistake - I made "" the default path for wasm page UIs when it clearly should have been "/". A small but important change.

WASM Support

You can now run Ooui fully in the browser as a WebAssembly.

The Ooui.Wasm nuget package contains a build step that generates everything you need.

New Controls, New Forms, Old Bugs Destroyed

Fix returning to pages without re-requesting them

Chrome likes to cache HTML and was making a new web socket
request without first requesting a new page. The server however
expires a web socket url after its first use.

To fix this, web socket urls have a rolling cache policy and
can be reconnected to.

Fixes #52
