 Improved lists when sorted by title. The New Titles page and
 any proglist sorted by title selects one representative row
 per title. This should be the earliest showing, however,
 MySQL's "GROUP BY" does not assure that the first starttime
 will be chosen. "ORDER BY" after the fact will only sort the
 possibly incorrect rows chosen by "GROUP BY". Therefore, all
 matching rows need to be SELECTed then the best row can be
 chosen in memory.

 The steps to fill the lists have been restructured. All
 matches are found with no GROUP BY. All lists, regardless of
 type are loaded into the sortedList. For plNewListings or
 titleSort, the list is sorted by title with the "best"
 showing first. The list is then pruned to leave just these
 "best" time slots. If titleSort is false, the list is sorted
 by time. Finally they are loaded back into itemList either
 forward or reverse depending on reverseSort. This means the
 sort functions don't need a reverse flag as the lists are
 forward until the very end.

 When comparing two titles that are the same, the "best"
 showing is, if the recstatus is the same, the earliest
 starttime. Or, the one that is recording, or the one that
 will record, or the earliest starttime. The result is that a
 recording in progress will be chosen, or else the earliest
 rsWillRecord, or else the earliest showing.

 So, I record several Reality series. If I go to Search
 Lists->Categories, choose Reality and press "2" for Title
 sort, all the titles where I have upcoming recordings appear
 in green even if it is not the very next showing that will
 record. Also, the New Titles lists will now be sure to show
 the earliest showing for each title except when a later
 showing has been chosen to record.

 Thanks to Hal Burch for his input.
