cf: allow changing folder of another account

Add a new -a flag to :cf. When specified, an account name is required
before the folder name and the focus will be changed to the
corresponding account tab before changing folders.

If the target folder does not exist, an explicit error will be reported.

Changelog-added: Change to a folder of another account with
 `:cf -a <account> <folder>`.
