Title:
  We should avoid use context property objects

Status in “ubuntu-ui-toolkit” package in Ubuntu:
  Confirmed

Bug description:
  Based on this doc: http://www.kdab.com/qml-engine-internals-part-3
  -binding-types/

  v4 engine binding is faster than v8 or javascript bindings. and:

  "The disadvantage is that the v4 engine can not deal with dynamic
  objects, for example those exported from C++ via setContextProperty()"

  
  What means that all objects exported to QML using setContextProperty will not produce V4 binginds.

  We are current exporting two basic objects to QML using
  setContextProperty. (units and FontUtils) , they are heavy used by our
  apps, we should change it to be a singleton.
