Jani Heikkinen 1a88b2f768 Updated license headers
From Qt 5.7 -> LGPL v2.1 isn't an option anymore, see
http://blog.qt.io/blog/2016/01/13/new-agreement-with-the-kde-free-qt-foundation/

Updated license headers to use new LGPL header instead of LGPL21 one
(in those files which will be under LGPL v3)
