Redmine › Download Button

We needed support for download selection of multiple version attachments as we have platform specific downloads for some products.
For this I created the attached patch (against trunk version).
For us the current patch suffices but I think for general application the 'multiple download’ support could best be made optional configurable through the settings. Also it might be nice if a regexp could be specified by which to select the presented downloads from the list of attachments of a Version.
Anyway, do what you want with it

Btw, I did not take ChiliProject support into account as we don’t use that, sorry.
