* Toolbar work: Tool Box & Color Tool Bar
  - Change from KToolBar to QDockWidget base
    - Nice side-effect: kpColorToolBar gets a QDockWidget resize grip
    - Lets us use QMainWindow::setCorner() so that Tool Box can take all the vertical space, since it can be quite tall with all its tool option widgets
    - Prevents KMainWindow from managing tool bar position so that we can force toolbars to be in a default and fixed place - this works around all the current quirks (due to the effects of QToolBar::setOrientation() no longer being virtual -- though, I actually saw an orientationChanged() signal now -- and probably other reasons):
      1. Toolbars staying on top of even non-KolourPaint windows when KolourPaint is not the foreground window
      2. Not being dockable when undocked
  - kpColorToolBar: use proper QSpacerItem instead of a fake widget (this looks better on e.g. Keramik style)
  - For component widgets, make them all do the following to avoid Qt layout oddities:
    1. setSizePolicy() themselves, rather than nobody doing it or leaving it up to the users
    2. Use setMinimumSize() instead of setFixedSize() and also don't use QSizePolicy::Fixed (don't know why this is required)

* Color editing work
  - Split queryClose() into queryCloseDocument() and new queryCloseColors()
  - Start fix reloading and modified-state to work (regarding modified state, what is missing is drag-and-drop affecting it and a lot of testing)
  - kpColorCollection
    - Introduce openKDE() method to replace ctor functionality and allow error-handling
    - Add "showOverwritePrompt" argument to saveAs()
    - Rename save() to saveKDE()
  - kpColorCells
    - Add colorCollection() and saveColorCollection()
    - Tweak ::Palette{Column,Rows}()
    - When there are >= 3 rows, reduce the heights of each cell only -- not the width -- and only to 17, not to 13 (so you can fit 3 larger rows, not 4 smaller ones; height of all the cells is 52)
    - Clicking no longer takes tab focus away from main view
      Testcase: When a text box is active, clicking to change the background color
                should not move the keyboard focus away from the text box.

* kpColorPalette
  - Add buttons to resize the color palette (TODO: revert this straight away since kpColorToolBar being  QDockWidget already gives us a resize grip, that is more intuitive)
  - Make sure kpColorCells are horizontally centered inside the scrollarea

* Documentation
  - Set target freeze date as Oct 21
  - Mark clearly as BETA
  - Document toolbar regressions

* Style, +/- debug
