Made csClass, csIface availible in regions.

csClass, csIface are now availible in () and <> regions.  Also availible
for class declerations (after : before }).

Fixes issue #1
Typo in csInherits region } for {
Constants (all caps) no longer csClass or csIface

All caps identifiers (constants) were being misidentified as classes or
interfaces.  New regex only identifies non all-caps.
