Don't throw when disabled socks config missing

Previously, the default config file generated by JM causes an error due
to not having `socks5_host` and `socks5_port`, which are commented out
since `socks5` is disabled by default. This commit makes those fields
optional when `socks5` is not set to `true` in the config. It also
makes `socks5` default to `false` if it is not specified in the config
for a given IRC server.
