New GUI browser to select one (or more) folders.

The browser lets the user pick one or more directories in a convinient
GUI browser. The initial directory list is read from a string
(separated by colons) and the resulting list is written back to the same
string (again separated by colons).

Note: The work was initially done by Jonathan Gordon, however I changed
it substantially so I claim autorship.

This selector is going to be used for autoresume and database scan folders.
