Instrument other quick-assist operations

[vazexqi]

Eclipse maintains a list of quick assist operation in its Help system.

We instrument the refactorings at the bottom of the table but not the ones at the top. In fact, the operations at the top of the table are not necessarily refactorings per-se but are nevertheless useful operations for code transformations that the developer might be interested in performing.

It might be useful to instrument and analyze how often those transformations are performed.
