[kevinchappell]

Improve style and functionality of Field Conditions editor UI and renderer.

• Ability to control visibility of Rows, Columns and Fields based on various conditions
• conditions:
  • value equals, contains, not contains or if checkbox is checked.
• adaptive editor hides and shows relevant condition options. Fo example if the IF condition is based on a checkbox, show the is checked option and hide value related comparators.
