Resolves #5

Download JSON & CSV File

• This PR adds a Download JSON and Download CSV option to bulk generate dialog.
• JSON works with everything
• CSV works with everything including Nested Arrays (One Level), String Delimiters (strings with commas, quotes)
• CSV works with Generated JSON in DataType, but keeps single JSON in single line. All generated JSONs are separated by line as done in a CSV file.

Extras :)

• Solved an unknown bug.
  • To reproduce, enter one item, any item to go into bulk mode, you can change the number of items here, then click enter instead of manually clicking generate.
  • when bulk action dialog is one, clicking enter to submit form also clicks the item from where the dialog was called making it call its onclick function which in-turn copies single value into clipboard making the bulk generated one useless.
