Replace DateConverter's and TimeConverter's use of deprecated constructors
--------------------------------------------------------------------------

         Key: DDLUTILS-57
         URL: http://issues.apache.org/jira/browse/DDLUTILS-57
     Project: DdlUtils
        Type: Improvement
    Reporter: Ken Weiner
 Assigned to: Thomas Dudziak 


Both DateConverter and TimeConverter use deprecated constructors of 
java.sql.Date and java.sql.Time respectively.  This request is to replace the 
use of those constructors with a non-deprecated one.

I am attaching a patch file that fixes both the DateConverter and TimeConverter 
to make use of the Calendar object to contruct the dates and times.

This patch also adds a check to the convertToString methods to check the type 
of the object, throwing an exception if the object is not of the expected type.

I also wrote some unit tests, DateConverterTest and TimeConverterTest  to 
accompany these changes.

Note: Before applying this patch, you could have called the convertFromString() 
methods with invalid text representations and the methods would have returned 
an unexpected date.  Now with the use of Calendar, this won't happen since the 
Calendar instance has been set to not be "lenient".  See 
DateConverterTest.testConvertFromStringWithInvalidTextRep() and 
TimeConverter.testConvertFromStringWithInvalidTextRep().  These test methods do 
not pass with the current code, but do pass after applying this patch.
