added timeframe page with scene, cloud, activity items
Merge branch 'master' of git.osinit.ru:timeframe
added timeframe page with scene, cloud, activity items, left/right pointers
update CMakeLists.txt
Implemented ActivityModel::data() and few other fixes
Fixed bug in ActivitySet::addActivity when filling end date in
ActivitySet is used for storing one day's activities. So hence some changes in API (ongoing). ActivityModel::addActivitySet() changed now too - to add activities to their corresponding set (depends on date). For now I added not really usable brute force solution just to get it to work
Fix bug when adding items to model
Made model emit signals when updating data and added beginInsertRows() when adding new lines
hash
добавлен вывод текущей даты

Conflicts:

Removed beginDate/endDate from ActivitySet
Changed the way nepomuk source gives data to model.
Removed useless getDate() from ActivitySet. ActivitySet is used now just as a wrapper class for list of activities in QML.
Changed the way row count is calculated. data() returns ActivitySet now, that acts as a wrapper to list of activities
getItem() now returns url of item
Replaced const ints used for model roles to enums
Changed ActivitySet to QML uncreatable type
Removed unused variable
Row count equals now to the difference between currentDate and the day of activity (in days)
