New User-Visible Features:
    * 'Merge Windows' feature.  This merges all of the existing Konsole windows into a single
      window.  (The opposite of detach view in a sense).  Only merges the views from the active 
      tab widget in each window at the moment. 
    * Split-view feature.  Splits existing view top/bottom.

New Front-end Progress:  
    * Make creating a new tab and window work in the new front-end
    * Add detach-view in new front-end
    * Added ViewManager class which manges views and view containers in a main window as well
      as creating new views and session controllers for terminal sessions.
    * Added SessionController class which provides the actions associated with an individual session and view.
      (including the Edit and History menus)
    * Menu items now working: Copy,Paste,Clear,Clear & Reset,Clear History,Configure Konsole
    * Wrote a widget for incremental searches in documents ( IncrementalSearchBar ).  The widget
      is closely modelled on the incremental search bar found in Firefox. 
    * SessionList class to provide the actions used to create new sessions in menus

Fixes:
    * Fix crashes with multiple views caused by trying to change the size of the 
      terminal image ( via setSize() ) after the user manually resizes the display
    * Update terminal size associated with pty when resizing display
    * Fix broken signal-slot connection in TabbedViewContainer
    * Check for a minimum terminal size of 1 line x 1 column when updating the terminal image
    * Ensure that internal array used by display widget to store terminal characters is always non-zero
      in size.  Also ensure that 'lines' and 'columns' internal properties are always > 0.
      Fixes crashes when display widget has a very small height or width.
    * Fixed crash with small display widget caused by TEWidget's count of used lines and used columns
      (usedLines,usedColumn fields) not being updated when the terminal image was made smaller.

Refactoring:
    * Further file renaming for consistancy between file name and class name
    * Make ViewContainer subclasses take a QObject* parent argument in their constructors
