SMT version 4.2

API Additions:

• Added the SMT.addZone static methods, which are shortcuts for SMT.add( new Zone()). There's an overload for SMT.addZone for each of Zone's constructors.
• Added Zone.getVisible(), Zone.getPickable(), and Zone.getTouchable() (Issue #210)
• Added an experimental replacement for TextZone called TextBox. It still needs a bit of work, but should be perfectly usable in its current state.

API Changes:

• Undeprecated the Zone key event functions.

Bug Fixes:

None

Other:

• Added two new examples that demonstrate the difference between the object-oriented and procedural styles of using SMT.
