Separating pure HTML and new ViUR Flare parts

[phorward]

In a local meeting last week, we decided about splitting HTML5 into two separate parts:

1. the pure HTML5 library including any base Widgets and HTML-parser
2. an separate framework called "flare" which provides further components, including
   • extended Widgets, for example the tools in html5.ext for dialogs, buttons, etc.
   • unified Ajax requests (network.py)
   • unified icon management (embedsvg.py) of some projects
   • ViUR related form management, including ViUR/vi styled EditWidgets
3. Existing projects need to be ported to use flare together with HTML5
4. HTML5 will remain as a library separately for several reasons, not only for modularity.

This issue serves as a reminder.

Flare was now started as a separate project with self-containted html5 library at https://github.com/mausbrand/flare. The html5 code bases of both libraries will be held synchronous.
