Add a fuzzy filtering among all projects, included into the one version

[svetlyak40wt]

Right now pages like https://ultralisp.org/versions/20190321044000 contain more than a thousand projects and it is impossible to check if some library was included or not.

It will be useful to add a text input which will do fuzzy filtering by project name. Probably this can be done on the frontend only. Or maybe we don't need to show the whole list by default, but instead to show only a search input and a total number of projects.

This also will be useful on the main page and on the page of the author.

Also, the search could be improved in future, when we'll add a "tags" or "categories".

There is also another task on doing fuzzy search: #23

I'll mention in passing that you might want to look into dgraph, which is an insanely advanced real-time distributed graph database, and it also supports fuzzy search.

I'm planning on investing massively in dgraph, "as soon as possible". (I've been in dire need of a database for years, and I don't like traditional SQL, and most NoSQL solutions seem wanting.)
