[Patch] Allow multiple navigation-synced instances on same page

[taa]

It would be useful to display two instances of the calendar on the same page; e.g., current month and next month, or current month and previous month, or a combination of both.

[taa]

Proposed solution: allow the year and month parameters to have a sign. If a sign is explicitly specified, then treat the parameters and an increment or decrement according to the sign. If the sign is not used, then the parameter is used as the month or year value.

Support is also added for month > 12 by incrementing the year, and month < 0 by decrementing the year and adding 12 to the month value.

A patch is included below

New patched version of WikiCalendar with year and month increment/decrement support

[Steffen Hoffmann]

Well, this is a nice suggestion indeed.

However, there exists a 'sister' plugin, WikiTicketCalendarMacro, that has been received considerable efforts to improve it for production, and I'm here to evaluate the possibility for incorporating key features of WikiCalendarMacro into it, even making it obsolete in the future.

With regards to #7564 I'd appreciate, if you could test the current version of WikiTicketCalendarMacro in your application as well and report back here. I can't make promises, but this might be a step towards finally solving this issue. Thanks for your patience and for still taking care.

[Steffen Hoffmann]

#8295 suggests a syntax for a calendar instance with offset to current time. I feel like this ticket is related, even more as I expect to have one hybrid Wiki(Ticket)CalendarMacro soon.

[Steffen Hoffmann]

Sorry for not pushing this further on.

Please follow-up on #8295, that I'd like to keep open instead of this one, because I feel discussion on the feature has advanced a bit more over there. And certainly the development target is 0.11 these days, that is already rather aged on its own, because Trac 1.0 is out for many months now.
