Removed unused lang from calendar/calendar.js
calendar-base uses its lang, calendar had unused copies of those files
Removed unused `short_weekdays` strings from calendar/lang
Only `weekdays`, `very_short_weekdays` are used
Fixed calendar's calendar-base-manual test
There was a call to a non-existing function,
plus the test's interface was a bit confusing /  misleading
Removed superfluous `weekdays` from calendar/lang
Use `datatype-date-format`'s weekday strings (which even support way more locales)

Fixed a bug in widget-stdmod
_fillHeight depends on this._currFillNode being set by _uiSetFillHeight
However, if the fillHeight node's content is set after render(),
_uiSetFillHeight doesn't set this._currFillNode, because the fill node doesn't exist (yet).

When the content is set, _fillHeight is called after('contentUpdate'), but since
this._currFillNode isn't set, it calls fillHeight with undefined.

The fix is to have _fillHeight getStdModNode() instead of relying on this._currFillNode
Checked in console build files.
