exposed as command the implementation by Anathema: kills all
processes using the tomb (denying it to be closed) and umounts
tomb (the commandline script) is not supposed to be interactive
we leave interactivity to be implemented by wrappers as tomb-open
so it should stop to ask the used if to slam, rather than offer
it as a command. now also tomb-status has the menu option to slam.
tomb shell command doesn't depends from X,
all GUI notifications are moved into tomb-open including USB key handling,
gksu has been dropped completely as a method to gain privileges,
there is a new -n flag to avoid processing hooks,
variable names have been sanitized, duplicate code eliminated,
documentation has been updated and the code cleaned up
we are very close to the 1.0 now
