multi_select filter for field with '+' symbol in

[joe-walsh]

When the field in the table contains a plus symbol and that field is selected from the filter that record is not found.
e.g. if the field in table was 'abc+def' when that value is selected from the filter it searches for 'abcdef' removing the '+' so no records are found
I'm using the 'chosen' select_type.

Probably its need to be escaped. Currently I'm away from pc and will be back in a few days. ..

Go grab the 0.8.3.beta.7 from https://github.com/vedmack/yadcf/blob/master/lab/jquery.dataTables.yadcf.js added escaping for several special chars...
