Use single-line Sass comments for copyright header

Sass single-line comments are preferable as they are removed from
CSS output (thus fewer KB's for end users).

We do not convert copyright headers for entry-point stylesheets
(default.css, legacy.css, scm.css).

fix text below subject jumps when hovering over subject
TimeEntries spent_on date display fix.

The detail view of logged time entries does not show the logged date

Using the date directive as an element tag with date-value set
seems to fix the issue.
