Improve edit summary of QuickReport

[lahwaacz]

Instead of just "add report" it should be "add report for [[Some page]]" to make searching the history a little easier.

As the edit summary is a configurable string, I've added support for %t which is substituted with a link to the reported article's title. To support future additional substitutions, % is in general a special character that is never rendered in the summary, unless preceded by another % (i.e. in order to render % it's now necessary to write %% in the configured string; to render %t literally it's necessary to write %%t and so on).

Note that your configuration can't be updated automatically, so you should change add report to add report for %t manually.

Done, thanks.
