Deprecated.In practice there is no way to ensure that this method will really be called.
The module might simply be deleted or disabled while the IDE is not running.
(In fact this is always the case in NetBeans 6.0;
the Plugin Manager only uninstalls or disables modules between restarts.)
Deprecated.Better to check specific aspects of the module's installation.
For example, a globally installed module might be used in several
user directories. Only the module itself can know whether its
special installation tasks apply to some part of the global installation,
or whether they apply to the module's usage in the current user directory.
For this reason, implementing this method cannot be guaranteed
to have useful effects.
