For certain types of tasks, it's helpful (and perhaps necessary) to be able to use Alembic's own tooling. We don't want users to have to use this often, but it's particularly helpful for developers. In particular, solving #5424 will probably require having access to Alembic's tool.

Attached is a patch which adds a gmg raw_alembic command. It's not recommended that everyone use it, but now it's an available option.

While debugging #5376, we noticed that attempting to access a comment which doesn't exist causes a server error. Ideally, we'd catch this and throw a 404 or just show the media page instead.

Here's an example to illustrate the issue, but these links may go away soon :)

There's an actual comment at this link. Following it works as expected.

Here I fat-fingered manually typing in the link, and I get a server error.
