Hopefully docs will be updated too. If you attempt to use this module
in an app today, it will attempt to store the app's config in:

~/.config/qt-labs.org/applicationName.conf

(as observed on 14.10 desktop)

Of course, this is not allowed on the phone due to AppArmor confinement.

The documentation here:
http://qt-project.org/doc/qt-5/qsettings.html#platform-specific-notes

makes it seem like we should be hitting case #2 for Unix:
$HOME/.config/MySoft.conf

but that is not what I observe.

Additionally, I can't seem to set my app's organization either, to try
and make it hit case #1:

Qt.application.organization: "com.canonical.achiang"

But then I see an error on the console:

Non-existent attached object

Finally, in general, it would be nice if the SDK provided some way for
Ubuntu apps to work better with AppArmor settings. As per:

http://developer.ubuntu.com/publish/apps/security-policy-for-click-packages/

The application will have read/write access files in the standard XDG
base directories. Specifically:

XDG_CACHE_HOME/<APP_PKGNAME>
XDG_CONFIG_HOME/<APP_PKGNAME>
XDG_DATA_HOME/<APP_PKGNAME>
XDG_RUNTIME_DIR/confined/<APP_PKGNAME>
---

However, reading environment variables from QML is prohibitively hard
(requires a C++ plugin). It would be better if the SDK provided
helpers for those specific variables so apps don't have to write a
plugin just to read those variables.

We have simply worked around this by hard coding: "~/.config" but that
is obviously not very nice, and might also fail in a language other
than English, where XDG_CONFIG_HOME != ".config" ...

Thanks
