Bump version to 0.6.2next

Automatically load the version from the version.py file

Prior to this the command would fail if the system contained logs which
contain spaces in their name

Make sure ~/.kamaki.log is removed when sensitive user data are
cleared out.

The function distutils.spawn.find_executable is not available in
Ubuntu 14.04

Make sure the user understands that this limitation has to do with the
input media internals and not with the place where the input media
itself is stored.

When adding a new image property, check if the property already exists
or if it contains invalid characters.

Add functionality for deleting image properties in the "Modify"
menu entry in expert mode and completely remove the "Delete" entry.

Update supported Ubuntu and Fedora versions

libguestfs prior to 1.27.9 will identify Oracle Linux as Red Hat
Enterprise Linux. Check for the presence of /etc/oracle-linux to
determine if the OS is Oracle Linux.

If the distro name as returned by libguestfs's inspect_get_distro was
redhat-based, since hyphens are not allowed in module names, importing
module redhat-based would create an ImportError exception, even if file
redhat-based.py was present. Although we don't have any redhat-based.py
module and the code will still correctly fall back to importing
linux.py this can be considered as a bug. In order to overcome this, we
replace the hyphens with underscores in the distro and osfamily names.
In the future, if we have to create a module for redhat-based distros we
will name it redhat_based.py.

When we wrap text to create a paragraph and print it in a dialog box,
make sure the lines will not get wrapped further by the dialog box.

If launching the guestfs helper VM fails, the library will throw a
RuntimeError exception. Don't treat this as an unhandled exception.
Convert it to FatalError but preserve the error message.

If an exception that we don't know how to handle gets thrown, make sure
the traceback is always printed in the command line. If the output of
the program is also saved in a log file, then make sure the traceback
gets printed there too.

Remove the warning about having swapped the names of the snf-mkimage and
snf-image-creator executables. Keeping this warning for one major release
was enough.

If a dialog widget exits in an abnormal way, we may end up having a
messed up terminal. Make sure that the terminal attributes are always
restored before the dialog-based version on snf-image-creator
terminates.

Add a short description of the program in the root page of the
documentation

Add instruction for importing the repository's GPG key before
installing the Debian packages

Conflicts:
	image_creator/version.py
	version

If the text was more lines that the height of the active region in the dialog
the 2 last lines were not displayed.

Those parameter can be used to control how many CPUs and how much RAM
the Windows VM should have during the configuration
