Mct#241

1. Added startup scripts to `MCT_DIST/bin` for Windows and Unix-like operating systems. Currently they're very simple, i.e. don't check whether Java is installed, etc.
2. Removed `startup-1.8b4.jar` from the root of the distribution archive (it was present in two folders, root and lib).
3. The startup script refers to `MCT_DIST/lib/startup-1.8b4.jar`. I had to update class path entries in `META-INF/MANIFEST.MF` to reflect this new location of `startup-1.8b4.jar`.
