BUG FIX: class EmailTextInput error

Was using lexicographicical order to to check dojo version, but this
is broken in 1.10 (1.10 < 1.[2-9]) so it now uses version_less_than().

NOTE: There are plenty of places where this is happening, but I'm only
fixing this in the places that are being used in my code for now.
Support for dojo 1.10.2
