Fixes for #1158 and #1310

[robgtsoftware]

This contains two fixes. First is a fix for #1158 to allow the JTACMonthCell to be programmatically subclassed without a need for a storyboard Second is for #1310 where I have added two new methods. One for scrolling to a given date in the year view and one for alerting the year view delegate that a month was selected. Extended the year example in the example app to show the new functionality. Also, make sure the default protocol implementations were visible to apps using the library
