Reorganized gradle scripts into subproject directories
Reformatted gradle scripts to be more consistent
Created :server subproject group
Deleted :mpqlib subproject due to inactivity
Hopefully this is a step in the right direction
Changed to standard gradle src directory structure
Changed some working directories to work properly with gradle tasks
Changed MPQViewer asset path to empty string
Added MSI (master slave instancer) to create child D2GS processes
This is intended to act as a temp structure for testing until support for actual servers are added where an API can generate proper instances
