Only looks in /usr/share for project wizards

TL;DR:
QtCreator should search for wizards in:
/usr/share/qtcreator/templates/wizards/...
/usr/local/share/qtcreator/templates/wizards/...
~/.local/share/qtcreator/templates/wizards/...

I'm creating project wizards for our SDK, and I'm noticing that QtCreator only seems to look in /usr/share/qtcreator/templates/wizards/...
I don't think this is great.

If our users `make install`, our install script would preferably install to the conventional /usr/local/share/qtcreator/templates/wizards/... location.
I also think QtCreator should search the conventional ~/.local/share/qtcreator/templates/wizards/... path since this is accessible without super-user permissions.

On a side note; looking at all the stuff under `share/qtcreator/...`, I suspect this problem may extend further than the project wizards...?
