Merged PR 189: Simplify usage of SmartComponent

- Added new Events :
  - AddContainer, AddContainerToSelectedContainer, AppendContainer, AppendContainerToSelectedContainer, SelectContainer, DeleteContainer
  - AddSymbol, SelectSymbol, DeleteSymbol
- Changed the component to an iframe (you only need to copy the whole dist now)
- Added callbacks to every methods in the component
- Create event listener on demand: no need to initialize the event listener!
- Update d.ts
- Added Fastboot and enable it by default on production build
