Remove code smell

[bogas04]

As the web app is moving towards complex features, components are starting to smell a lot and actions are coming up in the components.

I guess it's about time we use Flux sort of architecture to reduce code smell.

• [ ] See which methodology would suit SikhJS (MobX, Redux, ???)
  • [ ] Segregate actions
  • [x] Use stateless components unless really required
  • [ ] Implement the architecture
  • [ ] Integrate with IDB / FireBase (see #20 )
• [x] Refactor Components to use as little logic as possible
  • [x] Rely more on HOC to abstract logic into more re-usable components.
  • [x] Move to react-mdl #52
  • [x] Switch to React Router 4 #44

MERGED react-mdl branch is going well:

• Uses HOC for Loader and Toolbar. We can even do something similar for SearchCards.
• Lost 23% worth of size in bundle by switching to react-mdl

637acf3b060c0d6c11a30871ee4b36611bd44a21 uses function as children concepts for components like Fetch -> Markdown, Json -> GurbaniNow. This way we keep the fetching part primarily in Fetch.

Later we can implement caches at that level for better perf.

104 rewrite branch deals with it. Should ship with 0.6.0
