BUG: Remove forgotten Qt style

The style Macintosh (aqua) was still available on MacOS in the settings
even though it's a default Qt style.
Adding it to the list of Qt default style removes it.

BUG: Ensure qSlicerStyle is used when using SlicerApp-Real

When the launcher isn't used, for example when using SlicerApp-Real
directly, the plugin library cannot be found before the qSlicerApplication
is created. (QT_PLUGIN_PATH isn't set).

However once the application is started, the current location of the
executable is automaticaly added to the application library paths by Qt.

See Qt-doc: http://qt-project.org/doc/qt-4.7/qcoreapplication.html#id-a4ff2599-e40c-4218-82e7-14e570ebf822
"The directory of the application executable (NOT the working directory) is always added (...)"

Since this also corresponds to the location that needs to be set for the
plugins, the styles are automaticaly discovered.

BUG: Ensure Slicer dashboard packaging works if svn not in path

During recent windows factory maintenance, the path containing svn has
been removed from the PATH so that git bash could work with git svn.

As a side effect, dashboard windows packaging ceased to work.
