add optional arguments for better ticket event display control

[Steffen Hoffmann]

There are already some hints on changing display of ticket change events and where to go to change more.

However I suggest adding optional arguments to the macro call hand over control from the developler/!hacker to the user and provide more options altogether,
i.e. [open (default now)|openclose|close|...].

Closed #7234 as duplicate, but will take it as additional motivation to come up with a solution really soon.

I aim at embedding full TracQuery support, since this is a documented and maintained interface and will reuse a sophisticated solution instead of re-inventing the wheel.

[Steffen Hoffmann]

I'll start development in trunk immediately, stay tuned. Hope to get your beta-test reports here, once a solution is committed.

Any contribution is highly appreciated. If you feel up to the task and would like to cooperate, please write me right away to avoid unnecessary coding effort duplication.

Testing a beta implementation since last night.

This is not too complicated, but requires considerable code adaption, since I feel avoiding the old, now superfluous SQL ticket query is a must-have for performance and code sanity, since in the future we'll get all needed ticket data from TracQuery instead.

[Steffen Hoffmann]

TracQuery support has been introduced and fully enabled with changesets [8270:8272] can be tested with trunk right now. Once it has proven to be reasonably stable, this will be ported to 0.11 as well.

(In [8315]) WikiTicketCalendarMacro: Finish release of trunk features to maintained branches, closes #7172 #7390 #7410.

Release new ticket 'list_condense' function to 0.12 branch and backport it to 0.11 branch as well. Fix unreported bad inline CSS creation introduced with changeset [8263] for version 0.8.4 of 0.11 branch (0.8.5 was affected as well).
