Find mailbox by name considered harmful

[Peter Bloomfield <PeterBloomfield MindSpring com>]

In several places, Balsa searches for a mailbox based on its name. The 
search has a significant risk of returning the wrong mailbox, since a 
mailbox tree can easily have more than one mailbox with a given name. 
Thanks to all those who've pointed this out before.

Mailboxes can be uniquely identified by URL. In every place where 
incorrect identification can be harmful, either
  (a) search-by-name should be replaced with search-by-url, or
  (b) the user should be presented with a list of all matching 
mailboxes,
      showing where each is located in the tree, and asked to select 
one,
with (a) preferred.
