[3.5] Knight Champion - Fighter/Knight/Samurai/Paladin fix

[nonsi]

This is really nice.
I like the customization.
From what I could figure from this class, most is fine, but there are some things I'd change.
1. Good Fort seems more appropriate than good Ref.
2. To avoid forcing mental acrobatics and mechanics resolving on both player & DM, I'd place Bonus Feat in the Challenge list rather than the Honor list.
3. Pounce is meaningless at 5th level, unless you happen to have TWF, so it seems like you should change it to 7th.
4. One thing missing here is something that addresses action economy. You could give it something for that at levels 7, 13 & 19.
