InstalledPage: show size info on application cards
It's tedious to open up the extended application info when browsing the installed page sorted by size, so I added it to the application card on the installed page.
I'm seeing that I have one package showing no size info, and another with a negative size value. Though the negative one is showing the same in the extended description. The empty one actually has
a value in the extended description which makes me wonder if
delegateArea.application.sizeDescription is the correct variable to use.
