- made text size coordination among choice children optional using new "matchTextSize" attribute on <Choice>, default value is true or inherited from parent <Choice>
- improvements to <Choice> captionHeight parsing, including inheritance of parent values (only when explicitly specified)
- only parse "noColumn" on root <Choice>s
- Comment fix in TextFitView
- Parameters: non-required get* methods for integers, floats, longs and booleans now take non-primitive (i.e. nullable object) as default value
- made some getters on Project, Form and ChoiceField return immutable lists
