Request for change: replays & saves

[gingerbread]

It would be great if the history of the player is added to the autosave created when ending the turn in an MP game. Then we can review the turn and will not have to track the recon by fire on paper or screenshots.

Ideally, there should be a choice for a different name of the autosave file, could be entered in a text box located in the system options screen. Default 'autosave', but should be possible to change.

Even better if the name for the file entered is also remembered for the player in question so that the text box is populated with the last choice when opening the next turn, possibly with a pre-stepped numerator index.

Default save file name could be chosen when password is chosen.
