Major tune-up to the setup script!  It now creates a complete, BlazeLoader installed MCP environment that needs nothing else to work!

* Fix setup.bat not always working
* Fix unreliable file reading
* Fix not working in paths with spaces
+ Copies required libraries
+ Merges BlazeLoader sources automatically
+ Updates MD5s so that getChangedSource and reobfuscate do not pick up BlazeLoader classes
Commit because git thinks I need to?
Merge branch 'master' of https://github.com/warriordog/BlazeLoader
