Add Fixme sniff.

We do want this sniff to be an error, I believe.  That way it makes it
easy to put a comment in that reminds you to fix it before pushing it.
If the error isn't that important, then changing it to a TODO tag works.

Don't use interactive composer for build.

Github API rate limits can fail the default zipfile download for
composer packages.  Rather than ask for a username/password, let
composer fallback to cloning the codebase rather than using the zipfile.

This should fix broken travis-ci builds.

Don't use interactive composer for build.
Make our own Operator spacing sniff based on Squiz's.

The one in the squiz standard doesn't handle spacing before unary
operators, and doesn't touch the ternary operator or concatenation
operator.  It also has confusing rules regarding operators at the
beginning and end of lines.  This one simplifies things quite a bit and
hopefully results in more consistent spacing.
Remove arrayStart and arrayEnd methods in favor of bracket equivalents.
