Nicer Scale Filtering

Minification should be done with trilinear filtering, magnification
is still linear (the default) since this is the best available.
Project Settings

Change some project settings for more speed (at the potential cost
of binary size): Enable -O3, Link Time Optimization and inexact but
faster math.
Framework Copying

When building/installing, also copy the XADMaster and UniversalDetector
framework into the app bundle, so it is self contained.
