  Added Czech translations.
  Webkit: Fix missing namespace.
  qmake: subdirs template: make distclean target use QMAKE_DISTCLEAN
  qmake: fix warnings
  qmake: Remove macro and simplify string expression previously using it
  qmake: use isActiveConfig() instead of hand-crafting comparisons
  Fix missing namespace.
  Assistant: Fix spelling mistakes.
  Assistant: Use const references in foreach loops.
  optimization: get rid of QString::fromUtf16() usage
  document QString::fromUtf16() slowness
  remove duplicated calculation of length
  remove pointless conditionals
  micro-optimization
  optimize qhash()
