Merge lp:~milo/linaro-image-tools/disable-automount into lp:linaro-image-tools/11.11

[Milo Casagrande]

Disable automount, and enable it at exit.

As said on bug 1034853, this branch adds dconf calls in order to disable
and re-enable back automount options.

Before running the commands, a check is performed for the dconf command to
be installed.

[James Tunnicliffe (dooferlad)]

Looks good.

Unfortunate that we have so many PEP8 problems under the version shipping with Ubuntu 12.10. Will submit a patch.
