The Calendar, Memos and Tasks views use to do D-Bus calls to the backends on the main (UI) thread, which could result in UI freezes, until the operation was done on the backend (and server) side. This commit fixes that by invoking the operations in a dedicated thread. It has few additional advantages too: - operations can be cancelled - proper error reporting to a user - less code duplication between the views for common operations There had been fixed some performance issues when selecting/unselecting sources in the source selector as well.
