fix selectability of region-associated automation (i.e. MIDI)

Browse Source 
The fix here is really just dropping the use of _offset when computing the session position
of a control point. This was just an arithmetical error.

However, session_sample_position() was redundant and just caused more work, so this
method was removed, and only ::session_position() is now used.

In addition, several closely related places now use C++11 (or later) "auto"
syntax for iterating over containers, for cleaner looking code
