Always show year in Schedules Direct expiration date when important

[sphery <mtdean@…>]

The attached patch modifies the code that creates the DataDirectMessage (the subscription expiration message) so that it always shows the year when import--i.e. when the year is not the same as the current year--regardless of the user's selected DateFormat. Thanks to Marc Tousignant for pointing out the potential for confusion at ​http://mythtv.org/pipermail/mythtv-dev/2009-June/065350.html .

Note that this behavior exists only in trunk as 0.21-fixes always uses Qt::LocalDate format. [18444] changed it to use the user-defined date (and time) format for users who run mythfilldatabase in environments configured with a locale to which they're not accustomed (i.e. where month and day may be in the "wrong" order).

With the patch, if a user selects a DateFormat of "ddd MMMM d" (without year) and her subscription expires June 21, 2010, at 10:20 PM, the message will show:

Your subscription expires on Mon Jun 21 (2010) 10:20 PM

The parens were included to make formats like "MM/dd" look better ("07/21 (2010)" rather than "07/21 2010"). If the reviewer has a better approach, feel free to change the format modification.

If, instead, her subscription expires June 29, 2009, at 10:20 PM, the message will show:

Your subscription expires on Mon Jun 29 10:20 PM

(the year is not added as it's the same as the current year).

If the user chooses a DateFormat of "ddd MMM d yyyy" (which includes year) and the subscription expires on June 21, 2010, at 10:20 PM, the message will show:

Your subscription expires on Mon Jun 21 2010 10:20 PM

(year is not added as the specified DateFormat already contains the year).

Nice patch. I like how it will not display the year for expiration in the current year.

(In [20829]) Always display the SD subscription expiry year if different from the current year. Patch from Michael Dean. Closes #6679
