[PATCH] maildir: Create top level dir recursively

[Łukasz Żarnowiecki]

This patch fixes the situation when "localfolders" specifies path that
is more that one level deep and top directory does not exists.  Example
would be "localfolders = ~/Mail/a".  This especially relevant on the
first run.

In that case we would end up with unhandled exception causing
unexpected termination of the program.

Thread 'Account sync test' terminated with exception:
Traceback (most recent call last):
  File "/offlineimap/offlineimap/threadutil.py", line 172, in run
    Thread.run(self)
  File "/usr/lib/python2.7/threading.py", line 754, in run
    self.__target(*self.__args, **self.__kwargs)
  File "/offlineimap/offlineimap/accounts.py", line 258, in syncrunner
    self.localrepos  = Repository(self, 'local')
  File "/offlineimap/offlineimap/repository/__init__.py", line 82, in __new__
    return repo(name, account)
  File "/offlineimap/offlineimap/repository/Maildir.py", line 40, in __init__
    os.mkdir(self.root, 0o700)
OSError: [Errno 2] No such file or directory: '/Mail/a'

By replacing call to "mkdir" with "makedirs" we can simply create
directories recursively.
