Version 0.3's Class Change window with the new "Swap" button.
Note: version 0.4+ no longer shows a swap button since it's not necessary.
Description
Instantly swap your main class and secondary class when using the Housekeeper or Class Master NPC.
This reduces class changing from 8 clicks to only 2 clicks!
You might even consider it 1 click if you don't count clicking the NPC ;)
