Gamgi->Reset asks confirmation to restart GAMGI.

Because this is a very sensitive operation, users are not allowed to perform any other task until answering the question (not even consulting the Help).

Pressing Ok, GAMGI removes all the objects, cleans the history archives, exits all the actions that were taking place and keeps only a single empty window, as in the beginning.

However GAMGI does not reset the configuration information, so for example, changes in atom default properties and bond length limits, introduced by the user, are still valid after Gamgi->Reset.
