Updates for Warlords of Draenor

Added shortkey and checkbox to enable the use of WoD bait.
Fixed issues with lure and fish wait limit

Slightly increased time before lure is applied. This fix causes 1 cast
every 10 minutes to be without lure, but ensures that lure with 10
minutes cooldown (Nat's Hat) is off cooldown when applied.
The fish wait limit setting was not applied to the bot. It is now!
Default fish wait time

Increased default fish wait time to 22 seconds. 20 seconds will
occasionally be too short.
Textual clarifications

Updated some texts in settings to clearify what the numbers actually
mean.
Updated readme

Updated readme to describe support for WoD bait.
