MacOS Support

[michaelvlach]

Currently the qbs-autoproject does not support MacOS out of the box. The Qt detection does not work for it so it needs manually set path (or removal of Qt module).

Since I do not have access to a MacOS system I cannot add support for it. Basically what would need to be done is to add the support to:

autoproject.qbs

In the configuration probe there are standard headers detection (line 162, function detectStandardHeaders()) and Qt detection (line 179, detectQt()). In both methods there would need to be added support for MacOS as well as the current Windows and Linux.
