Remember positions of popup windows

[Nicklas Nordborg]

I got an extra monitor and realized that it would be useful to remember positions of popup windows.

The positions are remembered as long as the main BASE site is open.

Also added a configuration settings that allows a user to disable this feature.

Need to store the old positions as JSON strings instead of objects which doesn't work in IE. Gives error message: SCRIPT1717: The interface is unknown.

More fixes since browsers doesn't make the window the exact size as requested. Thus, when saving the previous position and then re-opening the window with those values it will shift slightly in size each time.

• Firefox: -1 pixel in height
• IE: +4 pixels in width/height
