qt and qtquick templates should be renamed

[Garyu]

I finally managed to install the qt and qtquick templates, only to discover that they are made to work with PySide. This should be made evident from the template name (i.e. pyside-template & pysidequick-template). I am working with PyQt4, which means I have to first install PySide and then do a lot of editing to use these templates, and it would have been nice to get a heads up about that before I started.

Thanks for testing the templates and for your bug report, it is really appreciated.

I'm a bit reluctant to add more technologies as a suffix to the template names, as:

* We cannot list every single technology that the templates use, which would make the template name unwieldy to even type. E.g. we don't call the 'ubuntu-application' template 'ubuntu-python-gtk-application'
* Listing all technologies would make the templates heavily dependant on them. E.g. right now the core ubuntu-application template uses Python and GTK. In the future, perhaps we will be using Python and Qt, and we'll promote the ubuntu-qt-application to be the main ubuntu-application template.

In the particular case of the Qt and QtQuick templates, Angelo, the lead developer, made some thorough research on whether to use PyQt or PySide for the templates, and following that, he made a decision to use PySide. Anyone can create another PyQt template, but I'd rather recommend to stick with the current choice and contribute to improving that.
