c77f3aa accidentially broke "sparse" updates (i.e. updates that do not
trigger during each update interval).
Introduce a new update parameter, "force", to model the use case "update
everything on SIGUSR1".
fixes#692
make it possible to toggle the display state of a widget between
"displayed" and "minimized" also for modules that re-create their
widgets during each iteration.
see #661
by default, allow toggling the minimized state of a widget via the
middle mouse and draw a single unicode char instead of the actual
widget, maintaining all states.
fixes#661
OK - so I have to admit I *hate* the fact that PIP seems to require a
subdirectory named like the library.
But since the PIP package is something really nifty to have (thanks to
@tony again!!!), I updated the codebase to hopefully conform with what
PIP expects. Testruns so far look promising...
