Retain cursor position after sync completes

[eykanal]

Currently, syncing disrupts editing of a note. Steps to reproduce:

1. Edit a note
2. Begin syncing the note
3. Before the sync completes, begin editing the note (i.e., continue what you were writing)
4. When the sync completes, the note is blur-ed (javascript definition of blur) and the position of the scrollbar is reset to the top.

I'll try to work on this on my fork when I get the chance, I'm putting this here simply to consolidate the issue tracking.

Yep - this is annoying. I also want to keep the sync from happening when you go to another tab and come back so you can Ctrl+Tab into another tab, copy something, come back, and paste (see #15) Google docs spreadsheets handles this really well.
