Remember the size and position of the diff viewer window.
This implements issue #41.

Make ESC quit the diff viewer, if the find window isn't visible.
If the find window is visible, ESC will first close that find window.

ESC closes the diff viewer if the find bar is already gone, otherwise the findbar is closed first.

Make sure the diff viewer can't be made smaller than useful.

Improve the search bar a little bit.

Add a 'find bar' to the diff viewer which does searching FF style.
