Removed wildcard processing from startGroovy.bat

Given a simple script:

    args.eachWithIndex{ arg, idx -> println "$idx - $arg" }

run with a command:

    > groovy test first second third.*

the Windows command line issues an error: *The syntax of the command is incorrect.*

I have modified the `startGroovy.bat` script to skip wildcard processing altogether. It's a very simple fix, but now the output is:

    > groovy test first second third.*
    0 - first
    1 - second
    2 - third.*
