f1eb3e97 - venvCmd.bat: allow executing a command when already inside an NVDA Python virtual environment.

venvCmd.bat: allow executing a command when already inside an NVDA Python virtual environment. This therefore allows running any of the high-level batch scripts (scons.bat, runnvda.bat etc) after manually ensuring and activating the NVDA python virtual environment with venvUtils\ensureAndActivate.bat. Developers thus now can either just run the high-level commands (letting everything happen transparently), Or they can ensure and activate the environment once with venvUtils\ensureAndActivate.bat, and then execute anything within the context of the environment, which may include those high-level commands. Note though this second way of doing this is still not the recommended way for most developers.
