[Feature Request] Add DevLogin support to client run configs

[ApexModder]

DevLogin allows users to authenticate their clients using Mojangs services at startup.

Adding DevLogin to any NeoForge mod involves the following steps currently.

While this is a simple setup, I think it would make sense for NeoGradle, and potentially other loaders too, to include DevLogin as a feature for their client run configs.
Of course this would have to be a opt-in feature, having it enabled by default wouldn't make much sense IMO.

I am thinking of adding a super simple boolean flag (authed true) to client configs, which when enabled

• sets the main class to net.covers1624.devlogin.DevLogin
• sets the program arg --launch_target to cpw.mods.bootstraplauncher.BootstrapLauncher
• and tells DevLogin to use the default auth profile via --launch_profile default
  There should also be an optional property users can specify to set the profile that DevLogin will use. This will allow users to authenticate their clients with multiple accounts.
  Maybe something like authProfile <profile> (if set also sets authed true)

I prefer DevAuth personally. It doesn't require fiddling with the main class. Alternatively, NeoGradle could handle login itself; it's not that hard.
