qml: display caret pos in status bar

[gwenzek]

As stated on #14 I'd like to display the caret position inside the status bar.

I tried to add a signal going from the LimeView Mouse Area to the main view.
The signal is fired on mouse pressed, but it's not caught by the main view.

I tried another way to register the signal handler, with a Component.onCompleted but it doesn't seem to be called either.

It's my first experience with qml, so I may be missing something simple. I read various documentation on signals, and created a toy application with a similar structure without problem. So I don't know where to look next. Any help would be welcome.

I'm not very familiar with QML, either, but I don't see anything obviously wrong. Maybe @zoli might have some ideas?

I think we should listen to OnSelectionModified event in frontendView and from there set status bar

This is duplicate of #3.
