quak files COLLECTION fetches that collection's files alone (closes #217)

`quak files` with a collection ID used to wait for a full refresh, which
on an empty cache fetched the files of every collection in the account.
It now reads the collection list, then that one collection's files
through the new `Library.freshFiles()`, and stores nothing. The files
print in the server's order, and no refresh progress lines appear.
`quak files` without a collection ID still waits for a refresh.

Some tests ran `quak files 1` to fill the cache, to show a refresh's
progress or to show what `-q` hides. They now run a command that still
refreshes.
