Correct path to main.qml in main.cpp
"Select a number set" now shows a dialog for selecting

Does not actually select anything yet.
Shows more than one item in the list for selecting number list

Needed to set the bottom anchor for SilicaListView
Selecting the number set works

Previously selected / user choise not visible, confusing!
Select number set delegate visually reacts to being tapped

Learned that ListItem indirectly inherits MouseArea and thus has
onClicked(). Code sanitized; now has visible effect on clicking. (That
was lost when using own MouseArea.)
Select numberset dialog now shows which one is selected

Current set preselected.
Deleting and editing sets works (almost)

Deleting sets works.
Selecting a set to edit and creating a new set with new valid name
works. Remorse popup for overwriting an existing set disappears too
quickly. Dialogs for invalid names not yet re-implemented. (Query Dialog
does not exist in Silica so dialogs from Harmattan do not work.)
Create set page uses Theme-derived sizes

... instead of fixed pixel count sizes

also added a validator to set name: an empty string is now marked as
unready
Merge branch 'sailfish_settings' into sailfish_settings2
Better looking about page

Moved application name and version to PageHeader. Tect no longer
overlaps the dots on the upper left corner. Added 2014 to copyright
years.
Added dummy cover
Merge branch 'sailfish_cover' into sailfish_cover2
Total scores show up on the cover
Heading fits in the cover

Achieved by setting the font family to that provided by theme. No idea
why it is not used automatically here.
