Add kvg:radical="jis"

After recent work on checking the radicals, I sent some email to Jim Breen about differences between KanjiVG's radicals and Kanjidic's radicals. Jim is using a reference called the JIS 漢字字典かんじじてん as the authoritative reference for Kanjidic, but this diverges from some other sources such as whatever Wiktionary et al are using. To incorporate this information into KanjiVG, I propose adding a value "jis" to the possible values of kvg:radical which would be the value of the radical as recorded in the JIS reference, and by extension in Kanjidic, which is electronically readable. This would allow consistency with Kanjidic as well as leaving the current values of "general" and "tradit" alone, in case someone is using them.

If nobody has any comments to make about this I'll go ahead and merge these and close the issue.
