Bug ID: 41716
           Summary: appwiz.cpl should have a function to report addon info
           Product: Wine
           Version: 1.9.23
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Wine should have a command that reports, for each addon:
* The addon name.
* The version of the addon Wine will automatically install.
* The system location where Wine will search for this version.
* The URL Wine will try to download.
* If Wine has downloaded the installer and cached it, the location of the
cached installer.

Appwiz.cpl already has a table that it uses to determine these things, so it
should be easy to dump it to a terminal.

The expected sha1 hash may also be useful, but it may confuse users of
distributions that build their own addons and have a different sha1.
