Add more formatting options to the code formatter

[THHamiltonSmith]

More formatting options for the code formatter page would make it more useful. js-beautify is the code formatted used, so properties from their documentation here will be helpful. Some examples of features that could be added include:

• Tab spacing,
• Indent on conditionals (if statements, for loops etc.)
• Wrap lines at certain length,
• Any other features that can be thought of.

Hey @THHamiltonSmith, I'm interested in this issue. Can you please tell where's the definitions of these functions?
