Eike Ziller 41b73594ad Add API for saving settings with default value ...

We should never actually write default values into the settings, because

- if the default value changes in a later Qt Creator version, the new
  default should automatically take effect if the user didn't change the
  value
- it senselessly grows the settings file

Add a QtcSettings class that extends QSettings by a
"setValueWithDefault" method, which does not write default values to the
settings, and actually removes the settingskey if the user switches back
to the default.

Use it at the places where we already do this manually.
