EE: No gui quickload

The EEs added a quickload button to some start screens, just like iwd2. We need to store the name of the last save that was saved in the config/ini (something like "Last Quick Save" with the value being the filename), so we can look it up on start up. Just deriving it at the time is not good enough, since there's an action that can prevent it — `ContinueGame`. And then we need to wire the quickload itself.

As a bonus, we can add a small button to the other games, so they can use the functionality as well.

Here's an old diff from chiv for the same thing; perhaps some of it can be salvaged:
