Store active zoom, rotation, and position

[KenLucke]

Please consider storing the zoom, location, rotation, etc., along with the prefs.

The issue is, when OctoPrint is reloaded, it loses all this (even during the same print), so I have to re-zoom, re-rotate, and drag the grid back to where I had it before the reload. A "reset to previous view on reload" pref could be added, so if people did not want to have this happen, they could choose not to do so.

BTW, I was told by the "other" team that there was no way to overcome the browser limitation on displaying gcode for very large files (in the built-in gcode viewer). Yet, somehow, you seem to have had no problem doing that (at least so far for files up to 420mb that I have tried). Good for you.

Yes, this would be awesome. Or at the very least, load up the gcode with it rotated so you look at the front of your print, not the right side.
