This command simply prints a random URL. A tag may be specified to limit
the search to that tag. In the Conkeror module this command immediately
loads the random bookmark in the current buffer.
- js/clark.js: If `error' is empty, return the value of `data'. This
makes it easier for some commands to use the result of the command.
Add `clark-random' to `clark_keymap'.
The McCLIM dependency will come back, but for v0.1.* it is not a
requirement.
Also properly require `cl-sqlite' by adding it in the `asdf:defsystem'
call.
