This is a stop-gap CSRF protection mechanism from unsophisticated attacks. It's to be considered a temporary solution until a more complete one can be implemented, but it should be sufficient in most cases for the time being.
See https://github.com/tonarino/innernet/issues/38 for further discussion.
Introduces `--hosts-path [PATH]` and `--no-write-hosts` options in `innernet`.
This could be further improved to have a persistent setting in a config file i.e. /etc/innernet.conf (which doesn't currently exist).
