[Request] Launch options prefix / suffix / syntax

[n1trux]

In Steam, you can use %command% to specify a prefix/suffix for launching applications.

So if you like to run hl2.exe -dx9 you can either input -dx9 or %command% -dx9. This allows you to prepend launch options, too, so you can launch the game with a wrapper. There's no official documentation on this (Volvo pls fix) but a bit of discussion on Steam's Linux github.

If you'd like to use libstrangle to limit a game's FPS in Steam, you could use it by entering strangle 60 %command% -dx9.

I would like this to be possible (and visible in the UI) for Bottles, too. To avoid confusion with familiarity, I propose that we'd use the same method Steam uses and replace %command% with the game's executable (or rather: with bottles' wrapper and the executable).

Alternatively you could use the command line to use a program to then run bottles which then runs an application, but that's not convenient and may confuse users who are less technical.

This may be easy to implement. I'm currently trying to implement libwine in Bottles and there is an task that should help to achieve what you need: bottlesdevs/libwine#3 (extracted from bottlesdevs/libwine#2)

This is now available with the latest unstable build, just using the %command% placeholder in the arguments dialog.
