Should I fix some rails < 3.1 related bugs or may be simple_form 2.0 will not be support rails < 3.1?
There are some problems with procs in `validates_format_of` and tokenizer option in `validates_length_of` https://github.com/rails/rails/blob/66a4beb0c9764238e1e8bed83aca88a397039bde/activemodel/lib/active_model/validations/length.rb#L19 (there is a default `tokenizer` option)
