[Development] How to create new Qt modules or tools

[henry.haverinen at nokia.com]

Hi all,

So far it has not been clear how you could start working on a new module
or tool in the Qt project. We've now created a wiki page for this
information here:

https://wiki.qt-project.org/Creating_a_new_module_or_tool_for_Qt


This page introduces the Qt Project playground (a low-barrier area for
experimenting with new ideas), gives some naming guidelines for modules
and tools, and documents the module repository structure.

Please review!

Best regards,
Henry
