Refactor Dialog class containing fonts: 

- the previous code has a _font pointer in derived classes, and a _font reference in the base class; this causes name collisions
- the Dialog class now takes a font reference, which is used throughout the hierarchy
- this simplifies certain code (setTitle vs. initTitle) and also eliminates clang warnings
