Fix for simple URLs

Changed URL argument extraction to use the edkURI tool so the kill ID can
be correctly extracted when using the simple URL format
(/kill_detail/123456/) instead of the default URL format
(/?a=kill_detail&kll_id=123456).
Increased settings input field size

Increased the settings input field size to fully accomodate the client ID
and client secret generated by CCP. Pure cosmetic and usability change.
