a 'BidiString' holds both the logical content and the visual reordered
version of the content of a string. this helps to reduce the number of
calls to reorder the string before drawing it (as introduced in the patch
from Ken Bloom) and to be more consistent in menus and textboxes (drawing
cursors and underlining text).
if someone changed the session.screen0.workspaces:<int> value and fired a
"reload config"/reconfigure-Command fluxbox crashed.
changes:
- cleaner way of reading in the workspacenames
- cleaner way of initialize the workspaces in BScreen()
- on BScreen::reconfigure we add/delete Workspaces to the
current screen until init-file and fluxbox are in sync
-> the user changed the initfile and pressed reload, so
imho he wants to have the changes in the init-file realized.
