2.0.0: Better collins query

This release is a breaking release for people who were use to using the
-: syntax for doing negative matches on keys such as key-:thatidontwant.
Now instead you will use key:~thatidontwant. This also applies to all
other collins query flags such as -p ~DEV. Which will return everything
not in the DEV pool. This also has a bug fix for the --limit flag which
I broke when adding the ability to pipe to collins query.
