Extend Qt Lite Configure Tool for Whole Qt Configuration

Current user flow of Qt Lite Configure tool is quite cumbersome: configure Qt, use Qt Configure tool to set the wanted feature flags, re-run configure, build Qt. To make usage of the tool better it should be possible to configure whole Qt using the configure tool. User flow would be: configure Qt using configure -tool, build Qt.

Typical configuration tasks like picking necessary toolchain paths need to be possible with the configuration. All options of ./configure need not be possible with graphical controls. The least used ones can be allowed with an extra string field for additional options. The dialog also needs to allow picking the modules to build.
