Version 1.5pre2 - Lots of changes & improvements

      AG fixed slowdown of operations that change the number of Total / Unread emails because QF was updated every time - now done asynchronously with a 1000ms timer.
         fixed TB3 folder tree did not scroll to correct position
         added new Option: show subfolders in popup menus
         added whole / striped tab option and backgrounds
         fixed: no more accidental menu popups when customizing toolbars
      improved "Change the order of bookmarks " dialog
         added scrollbars and animation to "change order of bookmarks" dialog
         added Postbox support
    open items tweaks in whole tab coloring (active, hover consistency)
  known issues 
  * sometimes the colors do not show up on program startup. Any folder modification (e.g. unread/read) or Category selection will make the color appear         
  * popup menus might close delayed
  * Change the order of bookmarks has the wrong height (should be 80% of its parent)
  -------------------
  Postbox specific
  known issues color submenu still has no colors
               some minor CSS errors

Approval notes

I have modified the times to setTimer to pass the warnings, to no avail.

The calls to setTimer are necessary in order to take the strain of TB when it is starting and doing folder operations. These operations (setting up the DOM tree and manipulating it using the user\'s CSS settings / updating the QF interface on Folder / Email operations) generally are perceived to operate much quicker when carried out asynchroneously.

The setTimer on the folder listener is the most important improvement over version 1.2 and I expect it to combat a lot of performance issues with slower machines - as such it is more of a Maintenance release, in spite of the number of new features.

I also made a big effort to have _all_ strings properly localized (including dynamic menus). 

New Features: The 2 main new features (recursive subfolders / full tab coloring) are originating from user requests. Postbox compatibility was also asked for by the users.

The full tab coloring feature has still some minor inconsistencies with the way Active / Hovered / Dragged bookmarks and font colors are handled - it is by default disabled.

the recursive subfolders is currently named \"experimental\" as there are some issues with sticking popups. I will research the feedback of our users before finalizing this.
