Bug 27290

	The Slovak(sk) locale was not present. This patch fixes it.

Fix: 

The locale is the same as cs_CZ locale, with one exception: the timedef
	file. The source for correct Slovak(sk) timedef can be found here (if you got
	it corrupted, get it from the URL in the header). It's essential, that 8th-bit
	is not stripped down:
