     folder.c

  Screen to display and manage all the users folders

This puts up a list of all the folders in the users mail directory on
the screen spacing it nicely. The arrow keys move from one to another
and the user can delete the folder or select it to change to or copy a
message to. The display lets the user scroll up or down a screen full,
or search for a folder name.

Returns NULL if list is retrieved, pointer to error message if failed

This is kept in a standards "CONTEXT" for a acouple of reasons. First
it makes it very easy to use the folder browser to display the
newsgroup for selection on ^T from the composer. Second it will allow
the same mechanism to be used for all folder lists on memory tight
systems like DOS. The list is kept for the life of the session because
fetching it is a expensive.
