Add qmake rules to install Subsurface

This is probably the most complex part of the new buildsystem. This
adds the following targets:

 - Linux:
   make install - installs to $(prefix) (default: /usr)
   The install path can be changed during make install time.

 - Windows:
   make install - installs Subsurface and its dependencies to
                  packaging/windows.

 - Mac:
   make mac-deploy     - populates Subsurface.app with the dependencies
   make install        - mac-deploy + install Subsurface.app to /Application
   make mac-create-dmg - mac-deploy + creates Subsurface-$VERSION.dmg
