EventInterface does not contain any methods to supply or retrieve message source information -- specifically the data supplied in the IRC message prefix (servername or user details in the form "nick!user@host", message flavour dependent.)

This is an issue because it is not possible to determine the source of a particular event (e.g. you cannot tell who has parted a channel.)

The phergie/phergie-irc-parser package returns all the relevant source information in its output. There are a few possibilities for providing this in EventInterface; perhaps these have been considered before?

• Add array getSource() and setSource(array $source) which deal with an associate array of "source information", keyed by specific type (e.g. "servername", "nick", "user", "host"),
• Add string getServerName(), setServerName(string $server), array getUserDetails(), setUserDetails(array $userDetails) which deals with the 2 source flavours separately,
• Add setters/getters for all the different sources of information (e.g. string getNick(), setNick(string $nick), string getHost(), setHost(string $host), string getServerName(), etc, etc.) This is perhaps the most user friendly, though these methods won't be providing anything when the message flavour is incompatible (e.g. an accessor to "nick" would return NULL for server messages.),
• Add string getPrefix(), setPrefix(string $prefix), which would handle the raw prefix. This wouldn't be particularly friendly, as additional parsing would be required. Note that it could be done in addition to any of the above, just to provide "raw" information, in case it's useful in any instances.

Method names are obviously open to tinkering in all instances. Happy to provide a pull request if someone suggests they're happy with any particular solution.
