[sailfish] reenabling the automatically mark as read option, fixes #62
[sailfish] fix for building the Release version
[sailfish] added option for white background on icons, this is the default -- closes #65
[sailfish] put the settings in a flickable, as there might be too many options
[sailfish] added the selected value to the font size slider, also show Labels such as Small, Medium, ... corresponding to the Theme object
spelling mistake
[sailfish] made the labels use RichText instead of AutoCheck (which as i understand only sets StyledText or PlainText)

test whether this affects the performance!! -- regards #64
[sailfish] made the hide dock menuitem to a show/hide dock toggle menu item
[sailfish] disabled the about and settings MenuItem in the FeedItems and FeedItem View -- regards #66
