Round some blockchain numbers

[oxarbitrage]

Hey, this explorer is looking great. I have a small suggestion, some values have too many decimal places, for example in the main page:

And in the blockchain info page:

I think it will look a lot better if you can just show lets say 2 decimal places and maybe the full number if you mouse over.

Keep the good work, i might give it a try to having this explorer locally and contribute with changes like this one but not sure when so you might be quicker.
