This is a second attempt to fix the problems addressed by 69bbe627a9.
Because table cell classes needed to use the same initialization code as the NS_initWithCoder methods, it was necessary to refactor the initialization code into separate NS_initWithCell methods and call them separately from NS_initWithCoder.
- Fixed case where no format strings are specified in xib (which ends up being an empty string).
- Fixed case where malformed strings file would not match regex.
- General cleanup.
Tests: CPRuleEditorCibTest, CPPredicateEditorCibTest, SmartFoldersDemo: a real world usage of CPPredicateEditor.
