Unify quoting in metadata.xml files for machine processing

Force unified quoting in all metadata.xml files since lxml does not
preserve original use of single and double quotes. Ensuring unified
quoting before the process allows distinguishing the GLEP 67-related
metadata.xml changes from unrelated quoting changes.

 Baudline is a time-frequency browser designed for scientific visualization of the spectral domain.  Signal analysis is performed by Fourier, correlation, and raster transforms that create colorful spectrograms with vibrant detail.  Conduct test and measurement experiments with the built in function generator, or play back audio files with a multitude of effects and filters.  The baudline signal analyzer combines fast digital signal processing, versatile high speed displays, and continuous capture tools for hunting down and studying elusive signal characteristics.
