ui: search view autocompletion

- Implemented autocompletion for the QtSearchView.
- Added: MessageFinishedParsing that will be dispatched by the Project after the parsing step is done.
- Moved the initial MessageActivateToken from the Project to the Application.
- Added getNamesForNodesWithNamePrefix() to GraphAccess.
