Improved Shortcut Names + New Shortcuts

This issue came up in this thread, but thought it could do with it`s own.

Here is what I suggest the changes are (with relevant comparison to keep the same):

-Insert New Row ---------------> Nudge Notes In Track
-Insert New Row in Column —>Nudge Notes in Column
-Insert New Row in Pattern —> [keep as it really does add a new row]

The new shortcuts are

-Nudge Row in Pattern [pattern number not effected, no new row addded]
-Pull/delete Notes in pattern up [Like Backspace is used now for track including delete]

-Noteoff/ smart noteoff across pattern

Maybe better names could be come up with but I think the grouping is better.
