feat(glossy): release 0.5.0

New feature:

`init-glossary()` now accepts a `format-term()` function which gives the
user control over how the short-form and long-form of the terms are
assembled based on the needed mode ("short", "long", or "both").

Change:

Default theme changed to `theme-academic`, which is probably more
generally useful than the prior (`theme-twocol`).
