Changes to most help headers to improve and normalize them. Fixed some bugs involving references to light speed constant. Changed KB, MB, GB and TB to be the decimal versions (kilo, mega, giga) and added the binary versions as kiB, MiB, GiB and TiB (kibi, mibi, gibi and tebi). Added a firkin to complete the FFF units. Fixed a few remaining name case errors that were lurking. Also added yd and oz aliases to yard and ounce.
