Merge lp:~charlesk/indicator-datetime/timezone-class-privacy into lp:indicator-datetime/13.10

[Charles Kerr]

Move timezone code behind a private Impl class

Simple cleanup done while working on other bugfixes.

This doesn't change the behavior of any code; just moves the implementation details of GeoclueTimezone and FileTimezone into private Impl classes.
