Reorganize the display + improvements for dimmed flags
- the whole upper zone is now dediacated to the main character line
- make sure eash flag has a dedicated non-overlaping area
- improve support for dimmed flags (not yet properly functionning since this
dimm state is actually stateful, so some major refactorings are needed to
properly handle this).
