Add meta tag with charset information to application layout.
Previously, our default HTML would validate properly, but would generate
a warning: it doesn't declare a character encoding.
According to [the spec][encoding-spec], if you don't specify an
encoding, a 7 step algorithm happens, with a toooon of sub-steps. Or, we
could just actually specify it.
Since everything else in Rails assumes UTF-8, we should make sure pages
are served with that encoding too. This meta tag is the simplest way to
accomplish this.
