As discussed in #sugar, deployers can choose between putting
activities in /usr/share or in ~/Activities depending on whether they
want to give users an easy way to uninstall and update activities.

To avoid space duplication in LTSP environments, ~/Activities can
contain symlinks to somewhere in /usr if the deployer wants users to
be able to uninstall and upgrade activities.
