* Replace the Color Box's "Reload Colors" button with a label stating the name and modified state of the color collection for these reasons:

  1. It takes less precious vertical room.

  2. Reloading is not that frequent an operation (undoing a color collection mutation would be more useful but is not supported yet anyway).

* Eat color drops (which are usually accidental drags from one of our
  child widgets) to prevent them from being pasted as text in the
  main window (by kpMainWindow::dropEvent())

* Remove kpColorPalette::colorCellsIsModifiedChanged() signal to reduce duplication

* Clear up comments about hiding the windowTitle() in both the Color and Tool toolbars
