-Older versions of nodejs will throw all kinds of different errors depending on which version you are running. This check should hopefully prevent confusion about why the explorer is not working by giving a clearer error message before the explorer starts
-More graceful shutdown of node cluster on 'npm stop' with better cleanup of resources on exit
-Added new stop_explorer.sh script which looks up the explorer port # via settings file and closes the application running on that port # instead of saving and killing the process by pid as it did before
-Added support for pm2 and forever using 'npm run start-pm2' and 'npm run start-forever' respectively
-pm2 is automatically installed when starting with 'npm run start-pm2' if it is not already installed
-forever is automatically installed when starting with 'npm run start-forever' if it is not already installed
-Updated existing npm commands in package.json by replacing hardcoded 'node' with '$(which node)'
-/path/to/nodejs changed to /path/to/node in the /settings.json.template, /lib/settings.js and /scripts/sync.js files
-README updates:
-Added a new 'Start/Stop the Explorer' section
-Added PM2 instructions to the 'Start/Stop the Explorer' section
-Moved Start/Stop Explorer instructions to the 'Start/Stop the Explorer' section
-Moved Forever instructions to the 'Start/Stop the Explorer' section
-/path/to/nodejs changed to /path/to/node
-Some additional small misc fixes
-I figure this should be changed now while it's fresh on my mind and may come in handy down the road to have the ability to auto-run 'npm update' when new packages are added and/or to more easily do any other future pre-run processing
