Adding folders now follows Windows ordering

As per issue #11.

Was causing problems adding folders numbered 1...999 rather than
001...999.
Moved tokenize to utils

Didn't see you had a dedicated file for utility functions, moved
tokenize to utils.

Added "re" reference to utils.
Updated profile for Kindle Paperwhite

As per issue #10
Auto set book title to image directory

When adding an image directory set the book title to the name of the
directory (which is usually the name of the manga/chapter)

Fixed a slip with isdir
Reverted recursive sort, opted for natsorted lib

Was having performance issue with very large directories.

This does have the issue of order "File (1)" before "File", have raised
an issue with natsorted.
