Subject: Add WHOIS and config parsing

Now users can query each other

Plus, server info and creation date can be changed without recompiling
using configuration file in IRC message format which is loaded on
startup

TODO: since readcfg uses IRC logic, handle() now should be able to deal
with commands ending with simply \n
