List sizes

[PanderMusubi]

For address book, list total number of name-number entries. For SIM, list total capacity and number of used entries.

Android does not provide a way to get SIM total capacity, unfortunately. The only way to get it would be to insert contacts until SIM says no, and then delete them. Which is a long and unsafe operation. For that reason used numbers count for both SIM and phone are a bit useless.

I will consider adding this as an option.

instead of showing x (contacts) out of y (maximum contacts), only show x
