Add a restart button to the pause menu

[cbruegg]

I find myself restarting / resetting the emulation quite often to go back to my last save (i.e. an actual in-game save, not through Delta's save state feature). Currently this requires going back to the main menu, tapping on the same ROM and finally pressing the Restart button to confirm.

This PR adds a restart button to the pause menu. As it's a rather destructive action, pressing it will still show an alert asking the user to confirm, but this still streamlines the process.

I'm very inexperienced with Swift, so if there's anything in need of improvement here, let me know and I'll be happy to fix it.

The replay button icon has been taken from Material Icons. It's Apache 2-licensed, which should be compatible with AGPL.

Sorry to bother, did you have a chance to look at this yet? Thanks!

Hey @cbruegg. I'm looking through this PR now. This isn't a bad idea at all, it's made me think of making the in-game Delta menu customizable and adding your button to the list.

Do you have any other ideas for buttons we could add to the in-game menu list aside from your added "Reset" button?

[lonkelle]

Would you mind adding a screenshot of your new button on here?

Your pull request inspired me to write this card btw: https://trello.com/c/JgDxONsL/207-setting-customizable-in-game-menu-button-order-and-remove-add

Hi @lonkle, sorry for the delay - my past week has been really busy. Here's what the feature looks like:

Other buttons I think could be useful:

• Quick Save: Creates a new save state without having to open the save state menu
• Quick Load: Loads the most recent save state. There'd need to be a way for the user to undo this when pressed accidentally. I haven't quite figured out how that could be made to work smoothly.
• Toggle all cheats on/off
• Fast Forward without emulation speed limit (or at least 2x of the usual limit)

Making the menu customisable sounds like a great idea. Ideally it would also be possible to assign gamepad shortcuts to the menu items.

Those were great suggestions, I've added them to our roadmap:

• https://trello.com/c/BTvdcooT/237-enhancement-be-able-to-map-gamepad-buttons-to-in-game-menu-items
• https://trello.com/c/BA0GmZ6M/238-enhancement-give-the-user-the-ability-to-undo-an-accidental-quick-save-or-quick-load

Tell me what you think about my solution for "undo-ing" quick saves and quick loads. Likewise, you're also featured on the Trello roadmap if you look at the "Ready to be Merged" list (this PR is on there).

Lastly, what does "Fast Forward without emulation speed limit" mean? Isn't that what fast forward is, removing the speed limit? Or are you saying you just want variable speeds?

I think the temporary 'undo' buttons sound like a good solution :)

That's cool, thanks!

As far as I'm aware, Delta currently has a hard cap for the fast forward speed, probably to avoid making it unplayably fast. Sometimes though I'd like to really go as fast as the CPU allows, e.g. to hatch eggs in Pokémon games.

Good suggestion, I added your unlimited speed option to this pre-existing Trello card: https://trello.com/c/100N36tE/14-setting-variable-fast-forward-speeds

Is there anything preventing this from being merged? Seems like a useful feature

[cbruegg]

I've resolved the merge conflict, so hopefully? :) @lonkelle
