Fix several issues with the "EasyEditSpan".

- The easy edit span was displayed twice when in extracted mode. The orignal TextView now checks if it is in extra mode, and if so it does not display any pop-up
- The easy edit span was displayed before the view was layout causing the application to crash.

New feature:

- the span is automatically hidden after a timeout

I also renamed all the fields and classes to "EasyEdit...". There were still some field/class using an old name.
