If the summary widget is large, it gets a scrollbar. This looks really
weird, so prefer to grow the installer window instead. Discussed with
@sitter and settled on this solution.
ViewSteps can signal the ViewManager that they need more space (in pixels),
which may or may not be honored.
FIXES#778
This is done to support both Pythonic and Qt style method names, i.e.
both "isNextEnabled" and "is_next_enabled" is ok in a Python module.
Also better documentation in PythonQtViewStep, and stub for
setConfigurationMap.
Finally, proper handling of PythonQtViewStep Python-facing basewidget:
with this change, a call to PQVS::widget() only triggers a widget
relayout if it's necessary, and leaves it alone otherwise.
Now linking with -Wl,--no-undefined!
Moved find_package KF5 from the root CMakeLists.txt to the partitioning
module where it belongs. KF5 deps should be limited to plugins.
Lots of random fixage to make stuff link.
Removed CalamaresApplication reference from Settings.
Removed the use of AbstractPage, we don't need it right now.
