Remove functions deprecated in 0072

[bilderbuchi]

Some functions have been deprecated in 0072 (#1427 et al.). It's time to remove them at some point. I have tentatively scheduled this point to be 0074 (i.e. 2 releases after deprecation). ~ half a year (including inevitable delays) should allow plenty of time for people to notice the warnings.

List of deprecations:
ofVec*f::lengthSquared(), ofVideoGrabber::grabFrame() and ofVideoPlayer::idleMovie(),
ofPolyline::addVertexes,
ofGraphics: ofVertexes, ofGraphics: ofCurveVertexes,
ofQTKitPlayer::bind(), ofQTKitPlayer::unbind(),
ofAppiPhoneWindow::enableRetinaSupport(), ofAppiPhoneWindow::isRetinaSupported(), ofAppiPhoneWindow::isDepthEnabled(),

thanks!

you're welcome. I thought it would be smart to keep tabs/schedule on things. Milestones are perfect for this. :-)

I just updated the list of deprecations for 0072 in the OP.

so, it's been nearly a year now. Should we remove those deprecated functions with 0.8, or wait one more 0.x release? @kylemcdonald

[kylemcdonald]

let's remove them with 0.8.0
