Error in irc/client.js when user list has or had nickname "hasOwnProperty"

[Krinkle]

Both when the initial name change happens and for every unrelated NICK event after that, the following error is thrown:

TypeError: Property 'hasOwnProperty' of object #<Object> is not a function

This is a valid nick name on chat.freenode.net, presumably elsewhere as well.

This is exactly why I always use Object.prototype.hasOwnProperty.call(obj, prop) in my projects.

@Krinkle Can you submit a pullreq to make that file use that wherever appropriate, instead of hasOwnProperty?
