Rhino 1.7.10

(Note: This release is from April, 2018 -- I failed to update the GitHub release notes for it until 2019.)

This release fixes a regression introduced in version 1.7.7.2 that caused the
"propertyIsEnumerable" to throw an exception when used with String and typed array objects,
and possibly with custom user-written objects as well.

Issue 415

It contains a few other fixes:

Attila Szegedi (2):

• Make** as many CallFrame fields as possible final, initialize them in constructor
• frame.debuggerFrame != null || frame.idata.itsNeedActivation is identical to frame.useActivation.

Jeremy Whitlock (1):

• Missing properties are not enumerable when checking enumerability
