[Feature Request] Improve save data dialog

[Megamouse]

• I think the PS3 shows the save date and the file size in the save data dialog. Maybe we should do this as well.

• In addition, the cancel button in most dialogs seems to show "Back".

• Also, In a dialog that has yes, no and back, yes and no can be selected and confirmed with X. Back is O.

• The Save data dialog seems to load the time played later.
  Although i don't know which text is save description, and which is provided by the time info.

• Additionally, the confirm dialog is integrated into the save dialog.
  So we would need an extra step in our own dialog.
  Currently I simply reuse the message dialog utility for that.

• Adjust the PLUS icon (it seems to be way too big). Although I didn't check how it looks on real hardware

• Last but not least, the save dialog shows a loading screen with completion notification that we could implement.
  Although it seems useless in the current day and age with fast drives and SSDs.

File size is there because the PS3 had very limited hard drive space (20/60/80 GB for early models) and thus you had to be more careful about how much data you're storing on it. Also, it didn't have a file browser or other external software with same capabilities as rpcs3 users have on their operating systems. I don't think adding it will provide any useful information for our users.

Date when the save was created would be useful though.

I updated the issue.
It should now provide a more detailed task list.

Correct me if something is missing or plain wrong (I simply googled for PS3 gameplay, since mine is at some friends)

Some tiny other issue: I think the + Icon to the left is waaaaay to big.
Maybe someone can provide a couple of screenshots on how the actual "Save" dialog looks, or better yet, a video sample of the whole save process?
