[Bug 24390] New: Config files (mostly ~/.local/share) need a severe cleanup

http://bugs.winehq.org/show_bug.cgi?id=24390

Summary: Config files (mostly ~/.local/share) need a severe
                    cleanup
           Product: Wine
           Version: 1.2
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Right now, removing a Wine install folder (a wineprefix) leaves a lot of config
files behind it (menu entries, mime types...) which can't be easily removed due
to its sparseness.
The most elegant solution would be to put all these files on a special folder
inside the wineprefix, and symlink the needed ones on the right config folder.
This way, removing a wineprefix would just result on some broken links, which
could be taken care of by a special script.
Additionally, winecfg should have options to not create them.

Some of those files/directories are:
1> ~/.config/menus/applications-merged/wine-*.menu
2> ~/.local/share/applications/wine/
3> ~/.local/share/applications/wine-extension-*.desktop and
~/.local/share/applications/wine-Programs-*.desktop (the latter is
locale-dependent)
4> ~/.local/share/desktop-directories/wine-*.directory
5> ~/.local/share/icons/ (mostly all of them)
6> ~/.local/share/mime/application/x-wine-extension-*.xml and
~/.local/share/mime/packages/x-wine-extension-*.xml

(Some, but not all, of these entries are listed on
http://wiki.winehq.org/FAQ#head-9893ae50079ca7a959258f0bc9a17aaf2e69b391)

I don't know what most of them do, but:
(1) and (4) should be replaced by symlinks and put on the corresponding
wineprefix.
(2) should contain one directory for wineprefix, which would be a symlink to
the actual directory. This would result on a separate "Programs" entry for each
wineprefix. (Instead of Applications > Wine > Programs > FooSoft > Run Foo, it
would be something like Applications > Wine > Foo prefix > FooSoft > Run Foo)
(3) What's this??
(5) should be on each wineprefix, with the corresponding .desktop file pointing
to them.
(6) should be replaced by symlinks, and, if possible, put them on a directory
and just symlink the directory. Or, in my opinion, could be totally removed
from Wine, Linux's mime type detection works fine, thanks.

There should be a script that rearranged all these files on the corresponding
wineprefixes. In order to do this, the `env WINEPREFIX="..."` string on
~/.local/share/applications/wine/.../*.desktop can be useful.
