Beginning fix for web directories
Avoid using chroot for webserver here, since affects location of files served from webservers inside the simulation.
Correcting a comment
Better logging of TCP proxy settings
Remove print statement
Merge branch 'webdirs'
Weblink is served properly from webroot, while internal (simulated) webservers are served relative to the node file.
Merge branch 'master' into refactor/backplane-tests
