Allow groups to be an array or a string - Fixes jquery-validation#479

Field names can contain spaces (as they are a CDATA type). This causes problems with groups, as the string listing the fields is split on spaces.

This commit allows the groups option to be either a space-separated string or an array of strings so that field names with spaces can be added. It also adds a unit test to ensure that both string and array based groups are processed into the same data structures.
