Daniel Imms 6456f85788 Disallow running as root without --user-data-dir ...

This commit adds the --user-data-dir argument which allows a custom data dir
for Chromium's user data. This is useful when running as root on Linux since
the root user does not have read or write permissions for the ~/.config/Code
dir.
