Feat: massive changes to definition of components

This change switches back to the original `ctx<props>` syntax for
commponents. This lets lifetime elision to remove the need to match
exactly which lifetime (props or ctx) gets  carried to the output. As
such, `Props` is currently required to be static. It *is* possible to
loosen this restriction, and will be done in the future, though only
through adding metadata about the props through the Props derive
macro. Implementing the IS_STATIC trait is unsafe, so the derive macro
will do it through some heuristics.

For now, this unlocks sharing vnodes from parents to children, enabling
pass-thru components, fragments, portals, etc.

 This crate provides all the batteries required to build Dioxus apps.
 
 Included in this crate is:
+
 - Dioxus core
 - Essential hooks (use_state, use_ref, use_reducer, etc)
 - rsx! and html! macros
 
 You'll still need to pull in a renderer to render the Dioxus VDOM. Any one of:
+
 - dioxus-web (to run in WASM)
 - dioxus-ssr (to run on the server or for static sites)
 - dioxus-webview (to run on the desktop)
 - dioxus-mobile (to run on iOS/Android)
 
-
 Make sure dioxus and its renderer share the same major version; the renderers themselves rely on dioxus.
+
 ```toml
 [dependencies]
-dioxus = "0.2" 
-dioxus-web = "0.2" 
+dioxus = "0.2"
+dioxus-web = "0.2"
 ```
 
 ```rust
 use dioxus::*;
 
 fn main() {
-    dioxus_web::start(|ctx, _| {
+    dioxus_web::start(|ctx| {
         rsx!{in ctx, div { "Hello world" }}
     })
 }
 ```

 Additionally, you'll want to look at other projects for more batteries
+
 - essential-hooks (use_router, use_storage, use_cache, use_channel)
 - Recoil.rs or Reducer.rs for state management
 - 3D renderer (ThreeD), charts (Sciviz), game engine (Bevy)
