Fix - The Forest

[ImKringle]

Description

As of now the File parse type reads both the serverPassword and serverPasswordAdmin section of the config.cfg as just the main server password. Doing this causes a crash on startup as two sections of the config are the same thing

This edit changes it to not include the serverPasswordAdmin in the config and instead sets it in the Startup Command

This edit is for:

1. Removes serverPasswordAdmin from config creation on install
2. Adds -serverPasswordAdmin {{ADMIN_PASS}} to startup
3. Removes serverPasswordAdmin from the configuration files section of the egg
