The example has been copied from okeanos-guides. However, some
of the example's steps have been ommited (e.g. the installation of
snf-image-creator). Also, the focus has been shifted from ~okeanos to a
run-of-the-mill synnefo deployment.

The older method of installing snf-image-creator from source is restored
and presented alongside the official package installation method.

Drop python installation method in favor of a simpler method using
packages from the apt.dev.grnet.gr repo.

As stated in commit b5053149, these
packages are not needed for the installation of snf-image-creator.

Remove python-gevent and python-dev from the dependencies list for
snf-image-creator. These two packages were needed for kamaki < 0.1
version, but now are obsolete.

This is the initial commit of the okeanos-helpdesk branch.
The main purpose of this branch is to:
* Move non-technical parts (e.g examples) to the okeanos-guides docs,
  where they can be presented in a more user-oriented way
* Correct minor omissions that okeanos-helpdesk has encountered during
  the testing of the image-creator tool

The program would crash when running in wizard mode if the account
or token where missing from the .kamakirc file.

This reverts commit 883e57b0.
Drop the greenlet support.

Needed by new kamaki, otherwise it throughs an exception at the end.

The former is older but there are packages for it in distros like
Ubuntu.

It has changed after the last major revision and was not updated.

This is a workaround for a progress bar bug, where the system may
stay with the cursor hidden if finish() is not called.

PBS has now bocome sh.

Thank you cven.

Add progress >= 1.0.2 as install_dependency, since this is the version
that fixed the empty progress bar problem.

Add missing sections

Add a part explaining the usage and input options of the
non-interactive version of snf-image-creator.

Add SORTORDER image property

Also add a basic readme file.

Create a new dialog_menu module to host all the "expert mode" code.
Check the code with a new version of pep8

Fix various typos in messages, add .gitignore file for
automatically produced intermediate files.

Every time you tried to reupload an image, the dialog displayed the
pithos url instead of the image filename as initial value.

Extend the mechanism to recognise events with value "button/power.*"
as power button events. It used to only check for events with value
"button[ /]power".

The function used to ignore directories when cleaning sensitive data

The account info was saved in the token field in .kamakirc
