JBIDE-18673 when livereload server is running browsersim/cordovasim should automatically enable livereload

if livereload server started - livereload enabled on browsersim start
Does this setting to true not then on next setup and livereload is not running result in a dialog to popup saying livereload is not started ?

I think to make this work we need to have  away to represent that livereload enabled has three options: Yes|No|Auto.

Yes - always enable. tell user if it does not work.
No - never enabled. user does not get warnings
Auto - enable if livereload available on startup. user does not get warning if it is missing.
