Fix for simple URLs & cosmetic change

Commit #1:
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).

Commit #2:
Increased the settings input field size to fully accomodate the client ID and client secret generated by CCP. Pure cosmetic and usability change.
