Midi Editor: Remember last used zoom and stable default zoom

Currently the midi editor sets the zoom level depending on the sized clip. So if its just 1 bar long, the initial zoom level is close. If the clip is stretched it remains at the initial zoom level.

However when a clip is inserted that is longer (5+ bars) the zoom level is way too far out to actually insert/edit any data, meaning the user has to immediately zoom in before doing anything.

Example: http://i259.photobucket.com/albums/h...eaperzoom5.gif

Requesting

1) Initial zoom level is a reasonably zoomed in enough to be able to atleast see 16th notes, regardless of the size of the clip.

2) When a clip is closed, the zoom level is remembered. When any clip is opened, regardless of if it is a new clip or has been opened before, the zoom level of that clip is the same as when the midi editor was last closed.

This will mean users can work at the level they want to without having to constantly zoom just to see what data is on the screen.
