[Windows] .liferay-pid is not created

[lgdd]

It seems that the .liferay-pid file is not created under Windows when using lfr status. Therefore, it also makes lfr status and lfr stop fail because .liferay-pid doesn't exist.

Not really an issue since Windows will start Tomcat in another command window when using lfr start. So stopping the process is pretty straightforward by hitting Ctrl+C in that dedicated window. Same goes with the status (there's a window with Tomcat running or not).

I'll add a condition for Windows when running lfr status & lfr stop to provide an info message instead of an error.
