- Update to 0.8.1:
* the frame index 'e' refers to the first empty frame
(e.g. 'rule index=e' places new windows in empty frames, if possible)
* new setting 'hide_covered_windows' to improve the appearance
when used with a compositor.
* resize floating windows with the same command ('resize') as in
tiling mode and thus the same keybindings as in tiling mode.
Therefore, the 'fractiondelta' parameter to the 'resize' command
is now optional.
* keybind now checks that the bound command exists.
* cycle_all (Alt-Tab) now also traverses floating clients
* new setting 'auto_detect_panels' controlling the panel
detection algorithm.
* improved herbstclient tab completion for the fish shell
Bug fixes:
* Handle the regular expression "" correctly, since the grammar
of extended regular expressions does not allow "".
* Error handling for the lack of xrandr
* Fixes to make it compile on other systems and architecture
