We add clippy as our build — also rectifying the missing `plume-cli` build!
In the next step we follow clippy's advise and fix some of the "simple" mistakes in our code, such as style or map usage.
Finally, we refactor some hard bits that need extraction of new types, or refactoring of function call-types, especially those that thread thru macros, and, of course functions with ~15 parameters should probably be rethought.
With this PR, when JS is activated and WASM supported, the article editor will be dynamically replaced with `contenteditable`s elements. This makes the editing interface simpler and less like a regular form. It will also allow us to easily add visual formatting with native browser APIs (and to insert images or videos directly). Here is a little demo:
There is still a lot to do, but it is a good first step.
Fixes#255
* Allow customizing max form size from env vars
* Add error page for unprocessable entities
And change default http port to 7878
* Improve char counter: under the editor, more discrete, and give it a default value
Rust can compile to WASM, so let's use it for front-end code as well.
To compile the front-end:
```
cargo install cargo-web
cargo web deploy -p plume-front
```
