Fix AOT/Prod Build

Fixes

• Finally fixed AOT, which was a blocker on building for Prod/AOT.
  • You can now run ng build --prod (or --aot) without any issues
• Fixed some small styling issues
  • the most obvious one was a small a 1px left border showing beside header filter row

New Features

• When adding a new row to the grid, it now scroll to first row (if not already at row 0) since adding a new item will always display & highlight it on first row
• Add extra classes for the Formatters which use Font Awesome for styling purposes
  • for example: .delete-icon: { color: red }}
• Add a new params property to Column interface so that you can pass extra arguments if you need to
  • that is especially convenient for passing extra stuff to a custom Formatter
• Add GraphQL complex object functionality (still in beta)
