Ability to reference nested properties in fieldName using:

                 fields: {
                     "FieldName.NestedName": {
                         title: "Title"
                     },

your pull request got me thinking. i had a problem with my ajax side complaining that uid was ambiguous. but i saw your syntax here and wrote the field name out as "p.uid" { ... jtable guts here ... } and bam! no more ambiguous error from mysql. thanks!
