[FIX] misc: Babel; handle 'kur' (kurdish) locale

Issue

	- add a new language with locale code KUR (for Kurdish)
	- print any report with a datetime on it (RFQ for example)

Cause

	Babel (version < 2.7.0) does not handle locale "KUR".

Solution

	If wrong locale or not managed by Babel, try to fallback
	on server default locale.
	If still wrong locale or not managed, then fallback on "en_US" as locale.
