We're in an environment that uses network home dirs. In the past, we've convinced the Minecraft launcher to store things in the users' homes by calling "set APPDATA=H:\Documents\Minecraft\" in a shell script before launch. New launcher doesn't respect this setting, and just uses the default APPDATA location on C:. This is bad.

What I expected to happen was...:
Launcher would respect manual changes to the current APPDATA location.

What actually happened was...:
Launcher ignores this change.

Steps to Reproduce:
1. Call "set APPDATA=H:\Documents\Minecraft\"
2. Launch Minecraft.
3. Notice that all data files are being stored in the old APPDATA location on C:.
