Added hexchat_hook_server_attrs() and hexchat_hook_print_attrs() to the plugin
interface. This hooks are similar to hexchat_hook_{server,print}() except the
callback passes an extra argument with the (new) structure hexchat_event_attrs.

This structure contains attributes related to the event; by now it only contains
the server_time_utc member which is non-zero if server-time is enabled and the
server used this extension to pass a timestamp.

See issue #661.

(Note: this hooks are still not called by hexchat in this commit.)
