Data Builder Updates

We've made some improvements to the data builder to more easily explain fields and records.

• Main page for each table will now be the records page
• Edit field by clicking on the field name
• You can drag and drop columns to reorder them
• Add fields by scrolling to the right and clicking "+" or from the top field bar
• Delete fields by editing the field

In the meanwhile, the Fields tab will remain an option for those more comfortable working in fields.
