Large number of folders is truncated

[jjongsma]

 I have a large number of folders in my account. Rather
than expand to accommodated them, the folder list pane
truncates it with no way to access the lower folders

Clarification - this only happens when the main content
(i.e. the message index list) is shorter than the folder
list.  Apparently the footer is covering the bottom part of
the folder list.  Maybe add some space below the folder list
to force scrolling when it is too long?
