Well in an ideal world I wouldn't, but here I would like to keep the
option to do so basically because some of the controls eventually won't
be backwards compatible.

This could, however, be a feature for 0.40.1 or something. Because we
have to be backwards compatible and support controls in
~/.gdesklets/Controls/MyControl we could add optional support for
~/.gdesklets/Controls/MyControl/0.6 if the desklet has the version tag
in the display file. Otherwise just choose
~/.gdesklets/Controls/MyControl or the greatest of the numbers inside
that dir.

It would also speed up 0.40 since the Desklet control (perhaps the
future supported way of installing everything) does things according to
the older way, e.g. without the support for different versions.
