Focus per doubleclick

[franzlst]

It would be useful to set the focus in the graphical editor to a state, that is double clicked in the state machine tree.

insert by @Rbelder on 2016-11-11 Example1: if a scoped variable is double clicked in the graphical editor widget the scoped variable in the state editor should be selected and the tab scope_data_port-list-view set to the current_page in respective notebook. Example2: If a state is double-clicked in the state-machine-tree-view the state becomes focused/centered in the graphical editor/viewer.

Major sub-task is:

• [x] introduce a focus flag in the selection maybe best implemented by a signal.

other sub-tasks are copy'n'paste from issue #76 and suit this issue more
