r0.1.0 release of the Push Gateway specification

Because this is the first release, it has several moving parts to it:
* The version variables have been defined.
* The towncrier changelog has been prepared for future modifications.
* The templating has been updated to better support future versions of the specification.
* A release process document has been created.

+# How to release a specification
+
+There are several specifications that belong to matrix, such as the client-server
+specification, server-server specification, and identity server specification. Each
+of these gets released independently of each other with their own version numbers.
+
+Once a specification is ready for release, a branch should be created to track the
+changes in. This should be the name of the specification (as it appears in the directory
+structure of this project) followed by a forward slash and the version being released,
+followed by `_updates`. For example, if the Client-Server Specification was getting 
+an r0.4.0 release, the branch name would be `client_server/r0.4.0_updates`.
+
+*Note*: Historical releases prior to this process may or may not have an appropriate
+release branch. Releases after this document came into place will have an appropriate
+branch.
+
+The remainder of the process is as follows:
+1. Activate your Python 3 virtual environment.
+1. Having checked out the new release branch, navigate your way over to `./changelogs`.
+1. Follow the release instructions provided in the README.md located there.
+1. Update the changelog section of the specification you're releasing to make a reference
+   to the new version.
+1. Update any version/link references across all specifications.
+1. Update the index to list the version correctly.
+1. Add the changes to the matrix-org/matrix.org repository (for historic tracking).
+   * This is done by making a PR to the `unstyled_docs/spec` folder for the version and
+     specification you're releasing.
+1. Commit the changes and PR them to master.
+1. Tag the release with the format `client_server/r0.4.0`.
+1. Perform a release on GitHub to tag the release.
+1. Yell from the mountaintop to the world about the new release.
+
+### Creating a release for a brand-new specification
+
+Some specifications may not have ever had a release, and therefore need a bit more work
+to become ready. 
+
+1. Activate your Python 3 virtual environment.
+1. Having checked out the new release branch, navigate your way over to `./changelogs`.
+1. Follow the "new changelog" instructions provided in the README.md located there.
+1. Open the specification RST file and make some changes:
+   * Using a released specification as a template, update the changelog section.
+   * Use the appropriate changelog variable in the RST.
+1. Create/define the appropriate variables in `gendoc.py`.
+1. Update `targets.yml`.
+1. Update any version/link references across all specifications.
+1. Follow the regular release process.
