Add weekday abbreviation for open-today widget

RruleHumanizer gains WEEKDAY_NAMES_ABBR (Mo/Di/Mi/...) alongside the
existing WEEKDAY_NAMES and WEEKDAY_NAMES_ADVERBIAL hashes, plus a
self.wday_abbr(time, locale) utility mapping a Time's wday to its
RFC5545 code and looking up the abbreviation - keeping RFC5545
vocabulary in one place rather than teaching ContentHelper about day
codes directly.

ContentHelper#weekday_abbr is a thin wrapper passing I18n.locale
through. The partial now renders "Fr 19:00" instead of just "19:00",
joined with a non-breaking space so the pair can't split across a
line wrap.

Takes an explicit Time rather than reading Date.today, matching this
file's existing style of passing state in rather than reading it
ambiently - and staying correct if the currently-unused
calendar/_front_page_calendar partial (spanning six weeks, not just
today) is ever revived and reuses this helper.
