Adds new settings to ColladaUtils::ImportSettings and TSShapeConstructor::ImportSettings for persistence. Shape will now be re-imported with the original settings if the source art is newer or the cached.dts file has been deleted. Fixes material transparency blend mode assignment. Adds implementation for override scale, material prefix and always/never import options. Reads and applies metadata fields for scale and up axis from formats that provide it. Eliminates the assimp.log file and redirects log messages to console.log. Verbose logging is enabled in debug builds.
