Feature names for dojo/has don't appear after recent reference-guide build

[dylan]

After the documentation build for 1.10, the feature name tables no longer appear in the built docs.

Compare http://dojotoolkit.org/reference-guide/1.10/dojo/has.html#feature-names to ​https://github.com/dojo/docs/blob/master/dojo/has.rst#feature-names

This is broken with all versions of the docs (it used to work with all versions prior to the 1.10 build)

I found the cause, a subtle syntax error in the table definition.

Fixed in ​https://github.com/dojo/docs/commit/af33774ad1aeb4e288f1abfa7a81b0cd9eb69d2c and backports.
