Added:
proposal/myrmidon/src/java/org/apache/myrmidon/framework/exec/launchers
WinNTCommandLauncher.java
Log:
Converted the old WinNTCommandLauncher to new setup. There is no need to
extend ProxyCommandLauncher as it did not offer any benefit (because the 2 arg
version of Runtime.exec was always called)
