Add script to serve dev files

PVEDiscordDark/serve.py

+# Script to assist with PVEDiscordDark development
+#
+# By default serves HTTP on port 3000, any *.js request gets the JS script, any *.css request gets the CSS file and any image request gets corresponding image
+# Meant to be used with the "Requestly" browser extension to redirect PVEDD requests from PVE server to localhost:3000
