media-sound/pure-data: Rm 9999 version, rm symlinks to 9999, add 53.1

[NexAdn]

I see a few issues with this PR:

• The summary doesn't really tell me what it does. That makes it hard to browse through the PR list.
• Missing description of anything. This PR (or rather the commit) lacks a description of why some of these changes happen. In particular (looking at #523 as well) there is no explanation for why the live ebuild is deleted and why Simon is removed as a maintainer (which is something Simon should either do himself or ACK on, so I won't merge this in either case without Simon's approval).
• Your commit does two things at once, namely removing a maintainer and adding a new version. The changes in the Manifest don't match the addition of the new version, since they also drop the old entries as well.

My suggestion for a fix:

• Start with the master branch.
• Checkout a new branch: git checkout -b my-new-branch-name
• Add the ebuild for the new version. Following Simon's workflow, I suggest you stick with symlinks unless you have a good reason not to do so.
• Regenerate the manifest using pkgdev manifest.
• Test the ebuild.
• Commit your changes using pkgdev commit. This will run QA checks and write a proper commit description if everything goes well.
• Remove the old version, regenerate the manifest using pkgdev manifest and commit the changes using pkgdev commit.
• Push your changes to your personal fork.
• Create a new PR.

You might be able to switch this PR to a fresh branch, but I am not sure. Creating a new PR is probably easier. Depending on how you'd like to do it, keep this PR open or close it as you think is right.

Real quick, will get to more later, I didn't remove anyone. The interface told me there was no maintainer so that was just me trying to be helpful. You'll have to blame the interface for that.
