1) adds the ability to signal the grouping of JobTypes inside the JobQueueViewController (with compiler time option)
*** not implemented yet ***
1) adds a new property to "JobQueueElement" called "requiredActionByDate" to hold a NSDate; 2) renames "requiredActionBy" to "requiredActionByString" on "JobQueueElement"; 3) fixes "MockObjectFactory" to ensure that new "requiredActionByDate" is populated for all mock data
1) updates the XML message format constructed for "ETARequestedUpdateRequest" objects
1) adds a new version of the "JobQueueElementCell" entitled "JobQueueElementCellGrouped" -> this will facilitate creating a difference appearance for the JobQueueViewController's presented data when JobType grouping is enabled
1) makes a minor change to the labels displayed on the "Actions" section of the "JobDetailViewController"
1) deletes an unused property on the "JobDetailViewController" class
1) ensures that the newly renamed "requiredActionByString" is properly set from with the "JobQueueRequestDelegate" class; 2) makes sure that the "minuteDifference" between the current date and the "RequiredByAction" date is properly calculated in the "JobQueueRequestDelegate"; 3) ensures that the newly renamed "requiredActionByDate" is properly set from with the "JobQueueRequestDelegate" class;
1) fully implements NSMutableDictionary storage of "JobQueueElements" (thus allowing for JobType grouping on the "JobQueueViewController"); 2) changes made to both "theTableView" and the "searchResults" tableView to fully source all data from a NSMutableDictionary (vs. a normal NSMutableArray)
