updated lang. files
QML Models for categories, feeds and feeditems, not yet finished
quickfix for a few urls not opening properly
also show the notification when links in the text are clicked
made the FeedItem View work with the new QML Model
fixed the urls
added a global loading property, made all the pageheaders display its status and moved the update action to the pageheader (optional)
do not try to load erroneous feedicons every time, instead set the property of those feeds to '' making the pageheader provide more space for the title
removed all the numStatusChanges since they where not needed anymore and kind of redundant
fixed the ToggleShowAllItem so the updateView-Signal will not be called if set with the initial assignment
removed two log outputs
bugfix for pageheader not showing busyindicator when not having an update action
removing the duplicate call from FeedItemView, fixed the marking read when opening an item
