Import ui before threadutil to resolve circular dependency

Browse Source 
The `threadutil` module depends on the `ui` module, which cycle depends
on `threadutil` through the `Curses` module.

The `ui` module had been loaded before the `threadutil` module, breaking
the above circular dependency, but this was changed in a recent code
refactoring, preventing the `Curses` module from being loaded with the
following exception:

  File "./offlineimap.py", line 23, in <module>
    from offlineimap import OfflineImap
  File "offlineimap/offlineimap/__init__.py", line 20, in <module>
    from offlineimap.init import OfflineImap
  File "offlineimap/offlineimap/init.py", line 30, in <module>
    from offlineimap import globals, threadutil, accounts, folder, mbnames
  File "offlineimap/offlineimap/threadutil.py", line 25, in <module>
    from offlineimap.ui import getglobalui
  File "offlineimap/offlineimap/ui/__init__.py", line 28, in <module>
    from offlineimap.ui import Curses
  File "offlineimap/offlineimap/ui/Curses.py", line 27, in <module>
    from offlineimap.threadutil import ExitNotifyThread
ImportError: cannot import name ExitNotifyThread

Fix the above error by ensuring that the `ui` module gets loaded before
the `threadutil` module. Please note that the above fix is temporary,
and we should refactor the modules to not have circular dependencies.
