Protected Activities Support #2087

Activities deletion causes troubles during classes. Teachers from
Paraguay and Uruguay asked for a mechanism to protect activities
from being easily deleted.

This patch provides a mechanism that uses a gconf value to determine
which activities will not contain the erase option at the list view
palette.

The gconf value contains a list of activities bundle indentifiers.
