Transform graphical styles to Boostrap themes loadable independently
Extract styles (font, links & button styles...) and assets (logo, banner...) into dedicated themes (or equivalent) in order to:
- add the ability to apply easily a specific theme on an application (at compilation time or at runtime start, no matter)
- possibly reuse thoses themes in third-party applications
Default style and assets to be applied might be the Boostrap vanilla, as it is actually, overriden by a theme or another (RARe, WheatIS...) at compilation time (or runtime).
