Add filter parameters to milestone view

[techtonik <techtonik@…>]

Milestone view support only one milestone per page. Roadmap can display several milestones, but there is almost no control on order and scope of shown stats. The only option is to show completed milestones (show=all) or not.

I propose to extend "show=all" to allow queries like "show=^0.5" or "show=0.5|0.5.1", but it can create a conflict if somebody defines milestone named "all".

It can be convenient to extend milestone view as well to allow URLs like /milestone/6.0|6.2|6.4

Attached is a simple patch to select several milestones in roadmap using piped /roadmap?milestone=6.0|6.2|6.4 syntax. No advanced filtering using ~= or ^=

Why not. However, the current patch requires editing the page URL, which is not really convenient. For this to be included, some more thought should be given to the user interface side.

For example, the prefs form, in addition to the Show already completed milestones checkbox could have a Filter by name: field, which would accept a glob pattern. If you fill it with e.g. 0.11*, the roadmap module would show all the Milestone starting with 0.11.
