Rust Wrapper

[hassandraga]

I don't have enough time to finish the Rust wrapper here, if you have experience in Rust, you can tray to create a C struct webui_javascript_int_t, pass it to webui_run_js_int_struct() by reference, Another way is you can call webui_run_js_int() and give the necessary references.

This is to run a JavaScript from Rust by sending it to WebUI and receives the result.

Some wrappers I already finish it: Go wrapper example Python wrapper example

The _int mean interface.. probably I should rename it later.
