Alr.Commands.Init: change defaults for init project to release mode (#777)

I first decided to make the default better for developers (to catch as many errors as possible), but they end up in release crates which means that the performance is bad as well as the compatibility between compiler versions.

This patch set the defaults to max performance and compatibility.

This system is clearly not very user friendly, maybe we have too many options here.
Profiles like in Cargo could be better.
