Show approximate size of version to install

In the old UI one could at a glance see what the size of an app is. This is a very important number when your Phone is chronically low on memory or when you are on the go on a limited data plan or in an area with spotty network connectivity.

Installing a 200 KB app can be done on a whim mostly anywhere, whereas I want to think twice before downloading a 10 MB app just for taking a look at it.

This leads to me always expanding the version section in the new UI before doing anything else which I feel is unnecessary. Instead we could always show the size of just the recommended version.

(No idea where, I'll leave that to someone with design experience).
