add filters to TicketQuery from query string arguments

[shesek]

I'm using wiki pages and the TicketQuery macro to create ticket summary/overview pages, as I find them much more flexible than reports as I can have multiple 'views' on the same page (for example, have 'Assigned to you', 'Awaiting assignment', 'In progress', etc - each shows top 10, has different filters and ordered by different columns, all in the same page. Creating a page like that isn't possible with reports).

So - what I'm trying to do is create a per-project ('project' being a custom field I added) and per-components ticket overview using the Wiki. Instead of copying the wiki page for every project/component I have, I want to use something like wiki/TicketSummary?project=foobar and than read the query-string argument (project) to be used inside the TicketQuery macro and [query:].

I was trying to do it using IWikiSyntaxProvider and get_wiki_syntax (​http://pastie.org/private/evw1r9jkhcmq3m6jjgrojw), by replacing ${foobar} with req.argsfoobar, which works - but not inside other macros.

I think the best way is adding this functionality to core, by parsing custom arguments inside the TicketQuery macro and [source:] link, in a similar way to how $USER is replaced with the currently logged in user - but replacing them with query-string arguments instead.

This will give users better control and flexibility in creating their own custom ticket overviews, which can replace the reports in some cases if those pages could be dynamic and show different content based on arguments.
