* delete now knows a -f switch which forces detach or stop, if jail is attached or running
* restore added
* archive now saves the whole tag to archive to later identify the jail and backup date
* detach_images now also removes the soft link
* starting/stopping a jail moved to its own function
* I enforced some coding style guides
* * [ -n "string" ] is replaced by [ "string" ]
* * Command parameters are being quoted. This will later allow jail roots with spaces in its name
* * variable assignments are always enclosed by exactly one of ${}, `` or "", (except for cases like a=${x}/${y:-"z"}). This means that a="${x}" now is a=${x}
* * [ -z "string" ] && echo "Foo" is replaced by ["string" ] || echo "Foo", which normally reads out more naturally (i.e. [ "${jail_exists}" ] || exerr "Error: Jail does not exist." )
* * $? and $# are now always compared by -eq or -ne operators, not by = or !=
