Tracking issue: react-ification

[nrc]

Convert to using React

• Errors and build results
• error explanations
• build animation
• buttons/menus/search box in top bar
• menus
• breadcrumbs
• source view (including highlights)
• directory view
• search results (search and find)
• summary/docs
• history/state/back button use/return to build results
• URLs
• improve workflow (e.g., Use webpack to create a module as output #126)
• optimise (seems to be dog slow atm)

[nrc]

Refactorings for when initial work is done:

• move some exports from rustw.js to utils.js
• split components into presentational and container kinds
• general tidying up/factoring out common functionality
• smaller components - e.g., overlay for menu, etc.
• TODOs

@nrc any plans to rid of jquery?

Maybe I'm missing something, but as far as I can see it's used just for DOM manipulations + ajax call. DOM manipulations should be done by React. As for ajax calls, for me it makes sense to use some of fetch polyfills such as https://github.com/matthew-andrews/isomorphic-fetch. Which is pretty wide used in React applications.

Also I didn't find any other dependencies you use which would depend on jquery.

any plans to rid of jquery?

I would like to do this, and I've been removing bits as I go, but it has not been high priority. It would be great to remove the dependency. I'm not sure what is left, I don't think there are that many DOM interactions, and probably nothing that can't be replaced with native equivalents or React. I'd be happy to use fetch natively - I don't think we need to accommodate people on older browsers. Alternatively, we could use XMLHttpRequest - I don't think it is much harder than $ajax (I would like to avoid adding another dep).
