VoteKit v0.12.4

VoteKit v0.12.4

VoteKit v0.12.4 resolves GitHub issue #15 by allowing election creators to
include multiple clickable links directly in an election description.

Changes

• Every valid http:// or https:// URL in an election description is
  displayed as a safe clickable link.
• Multiple links and surrounding text retain their original order, line breaks
  and sentence punctuation.
• The create-election form explains that multiple links are supported.
• The existing Additional Information URL remains available for compatibility.
• Description text remains plain text; arbitrary HTML and non-HTTP URL schemes
  are not rendered as links.
• Regression coverage verifies multiple links, punctuation and inert HTML-like
  content.

This release changes presentation only. It has no database migration and does
not alter elections, voters, ballots, results or access controls.
