Change the thousands separator from comma to a space in the i18n/french.lang file

[AubinGaboriau]

It is more common in french to separate the thousands with spaces than using a comma. I was wondering if this modification could be made.

[DataTables]

I'm not sure as it would mean "1 2 3" would be detected as a number... Best option would be to use a thin space which DataTables will detect automatically.

Thank you for your quick answer ! I didn't though that the "thousands" attribute was used to detect numbers. I made a pull request changing the comma here. Looking forward to the next DataTables updates and thanks for this amazing jQuery Plugin!
