ZFSBootMenu 0.7.5

A previous release defaulted pool imports to read-only mode. Because of this, cloning a snapshot would fail. This release fixes that by detecting if a pool is imported as read-only, exporting it and re-importing it read-write. If the snapshot being cloned is encrypted, keys will be loaded again (from file or via prompt).

To control read-write behavior, the command line argument read_write has been added. If unset, this option defaults to 0, importing the pool in read-only mode. Set to 1 to enable read-write on imported pools by default.
