Additional formatting for readbility.

Adding a space after `,` in function variable lists.

Adding a space after `:` in object member assignment.

Spaces around `==`, `=`, `+`, `-` and other similar operators where more
or less feels appropriate.

Space after between the closing `)` and the opening `{` in function
declarations.

Possibly others that I`ve forgotten to mention.
Ident all the stuff because it's all in a function.
