Add maildir backend worker
Add the initial implementation of a backend for Maildir accounts. Much of the functionality required is implemented in the go-message and go-maildir libraries, so we use them as much as possible. The maildir worker hooks into a new maildir:// URL scheme in the accounts.conf file which points to a container of several maildir directories. From there, the OpenDirectory, FetchDirectoryContents, etc messages work on subdirectories. This is implemented as a Container struct which handles mapping between the symbolic email folder names and UIDs to the concrete directories and file names.
