Settings for weekplanner571

[Lildhansen]

This is a copy of this Pull request, which had to be reverted until the weekplanner had been updated. The weekplanner has now been updated in this Pull request

Description

necessary for work done on this branch: Expanded settings model to make 2 variables for handling the number of days to display in a weekplanner: a variable for the days to display in portrait mode and one for the days to display in landscape mode.

Since we changed the name of the variable nrOfDaysToDisplay, this will cause errors on the weekplanner, but to fix this we simply need to change the variable name of the weekplanner repository as well as the columns of the settings database

Also added a bool defining if days shown should start from today (relative) or Monday (absolute)

Also commented out a test dealing with offline mode, since it has been decided to ignore offline mode Related to #571 of weekplanner
