REVISION SUMMARY
  Improve realization and logic in command entry's prompt item animations.
  
  - Disable background colour manipulation
  - Set colour for `Queued` status similar to another statuses.
  - Change animation realization: from `QTimer` to `QPropertyAnimation`: simpler and convenient
  
  Also disable setting queued status for expression, which we run immediatly
  
  This commit also fix problem with QPropertyAnimation warnings (in short: we start animation, and immideatly remove animated object in `qDeleteAll`, of couse  before animation finished)
