Preview pane

[wobin]

Here's my patch to add support for a preview pane in the main window. The preview pane is user-configurable, and is disabled by default.

If the patch is not readable or properly cut&pasteable it can be fetched from ​http://eddy.introweb.nl/~robin/software/roundcube/20060908-r340-preview.patch.
