Add option to sort files with natural/numerical order algorithm + select collation

[dergrinch]

It would be nice if you add an option to sort the folder and files with the natural order algorithm. So sort e.g. 1, 2, .., 8, 9, 10, 11 instead of 1, 10, 11, 2, [...], 8, 9.

To clarify, Windows Explorer has a combined alpha/numerical sort, e.g.

file_1_normal
file_2_normal
file_3_normal
file_10_would_be_nice
file_100_would_be_nice

Thanks for the great work on filezilla - really appreciated!

It should also be possible to sort case-sensitive or case-insensitive.

Taken from closed #2675: It should be possible to select a collation to be used for sorting (see ​http://www.icu-project.org/).

Replying to dergrinch:

The number sorting would be nice to have but the alphabetical sorting is driving me batty. Ant, Bat, Cat, alligator, bug, crab should be sorted: alligator, Ant, Bat, bug, Cat, crab.

Natural sort has been implemented a while ago in 3.9.0-beta1. This ticket is since redundant.

Nonetheless, a cursory glance at your patch showed the following issues:

• Introduction of a glib dependency. New library dependencies need a configure check and the libraries to link against need to be updated as well in order to avoid underlinking.
• Lack of user choice which sort algorithm to use. In particular, natural sort has performance issues with very large directory listings.
