Might as well localize the name and description, since you've already got a `
_locale` directory with an English message file, and `default_locale` set.

Done.

You used `content_security_policy`! Hooray you!

I suspect you're neither using Flash at the moment, nor planning to.
`default-src 'none'; script-src 'self'; style-src 'self'` might be more
appropriate. It would, for example, prevent EVIL fonts from being downloaded.
Like Comic Sans.

Done, but I also added img-src 'self' for the "X" to delete rules.
