kanji-glasses-mode

Provides a minor mode for displaying the hiragana reading alongside kanji present in a buffer. This is accomplished using overlays, so the contents of the buffer are not modified at all.

Enabling this mode will take some time on a buffer with a lot of kanji present. To combat this, I've memoized the transliteration method, so it at least won't look up the same thing more than once.

Currently relies on kanji-mode for its km:kanji->hiragana method (which in turn relies on having kakasi installed) to transliterate kanji to hiragana.
