Increase epsilon for min_max tests
Disabled test for setting unexisting language
Setting non-existing language in the browser now works.
Uncommented test for setting undefined language
Added a way to uninstall a language definition

moment.lang(key, null) now uninstalls a language. That's mostly useful to
remove auxiliary languages added during test runs.
Added invalidAt function to get invalid unit index

isValid is boolean, so its not very helpful in determining which section of
a date is wrong. inavlidAt returns the index of the broken token, where 0 is
year and 6 is millisecond.
