[George Staikos]

CVS commit by staikos: 

- some i18n fixes
- get rid of unnecessary casts
- don't cast (QString)"foo".  Use QString("foo") if really needed, or better,
  rework it so it can be i18n("")
- (float)foo -> float(foo) etc
- const bool& is a bad idea and does nothing of benefit over bool.
