CONTRIBUTING now refers to the AM one (#30)

Replace the CONTRIBUTING file with a reference to the main one, for ease of
maintenance. Remove the currently unnecessary doctoc hook.

-## Contribution standards
-
-For more information on contribution guidelines and standards, see the
-CONTRIBUTING.md in the [Archivematica project][contribute-to-am].
-
-## Contributor's Agreement
-
-In order for the Archivematica development team to accept any patches or code
-commits, contributors must first sign this
-[Contributor's Agreement][contributors-agreement].
-
-The Archivematica contributor's agreement is based almost verbatim on the
-[Apache Foundation][apache-org]'s individual
-[contributor license][contributor-license].
-
-If you have any questions or concerns about the Contributor's Agreement, please
-email us at <[email protected]> to discuss them.
-
-### Why do I have to sign a Contributor's Agreement?
-
-One of the key challenges for open source software is to support a
-collaborative development environment while protecting the rights of
-contributors and users over the long-term. Unifying Archivematica copyrights
-through contributor agreements is the best way to protect the availability and
-sustainability of Archivematica over the long-term as free and open-source
-software. In all cases, contributors who sign the Contributor's Agreement
-retain full rights to use their original contributions for any other purpose
-outside of Archivematica, while enabling Artefactual Systems, or any successor
-organization which may eventually take over responsibility for Archivematica,
-and the wider Archivematica community, to benefit from their collaboration and
-contributions in this open source project.
-
-[Artefactual Systems][af-systems] has made the decision and has a proven track
-record of making our intellectual property available to the community at large.
-By standardizing contributions on these agreements the Archivematica
-intellectual property position does not become too complicated. This ensures
-our resources are devoted to making our project the best they can be, rather
-than fighting legal battles over contributions.
-
-### How do I send in an agreement?
-
-Please print out, read, sign, and scan the
-[contributor agreement][contributors-agreement] and email it to
-<[email protected]>. Alternatively, you may send an original signed
-agreement to:
-
-```text
-Artefactual Systems Inc.
-201 - 301 Sixth Street
-New Westminster BC  V3L 3A7
-Canada
