Register Qt 4.7 import on-demand, instead of at startup.
This is a slightly less awkward approach (keeps backwards-compatibility) while
speeding up startup for applications that don't use the old import path.
Also prints a warning to let developers know they should migrate their code when
possible. Completely disabling the Qt 4.7 import is still possible by setting
QT_NO_IMPORT_QT47_QML.
This takes around 10-15ms off a very simple "hello world" on my macbook.
As an added bonus, forward-port a similar approach to 4.8's
a26f545d8e25af74fb43d16c9afa79f6e04463e7 and don't register graphical types in a
non-graphical application as someone (very naughtily) apparently forgot to get
it integrated to Qt 5 first.
