Check permissions on startup
Issue #13 resolved
SSHGuard should check its ability to block and release addresses, whether using one of the firewall backends or modifying files. Most of these operations require
root, however, it would be silly to require
root permissions to use the "null" backend.
Ideally, when SSHGuard detects that it has insufficient privileges, it should fail as loudly as possible.
