Add wpsc_cookies and wpsc_plugins related actions to modify those settings (#582)

This PR adds four actions to modify wpsc_cookies and wpsc_plugins: * wpsc_add_plugin * wpsc_delete_plugin * wpsc_add_cookie * wpsc_delete_cookie These actions will allow WordPress plugins to modify the cookies and plugins lists used by WP Super Cache instead of the add/delete functions introduced in #574 and #580. Duplicate entries are removed. Example code: For example, to add a cookie name called 'euCookie': `do_action( 'wpsc_add_cookie', 'euCookie' );` To remove that cookie: `do_action( 'wpsc_delete_cookie', 'euCookie' );`
