Code formatting

[vishesh]

Just a suggestion for code formatting. I think the general Racket convention is to not have spaces b/w brackets. E.g the spaces b/w squares here:

rackt-org.github.io/src/app.rkt

Lines 139 to 140 in 11caf54

	($/obj [ store store ]
	[ dispatch dispatch ])])

and there is some inconsistency, on by not having space in some cases. E.g:

https://github.com/rackt-org/rackt-org.github.io/blob/master/src/app.rkt#L154-L155
