A couple minor bugfixes today: 2 rare bugs that could cause test failures and prevent Statocles from installing, and now the default site layout explicitly adds a charset meta tag, since Statocles writes all its HTML as UTF-8.

Full changelog below...

• remove useless test line
• fix store warning when given no content
• fix yaml remedy checks for YAML::Syck (#460)
• add test for template comments
• Specify UTF-8 encoding in site layout
