Ctrl + Z and (Ctrl + Y and Ctrl + Shift + Z) support (#358)

* Ctrl + Z and Ctrl + Y support

currently for Bazaar and AH search along with the search bar.
(might have issues as my brain jumbled up during the making of this
and also probably missing a few places that could use it.)

* Ctrl + Z and Ctrl + Y support but on a bigger scale

Removed it from Auction and Bazaar search and created a new mixin for GuiTextField containing the Undo (Ctrl + z) and Redo (Ctrl + y) action.

* Ctrl + shift + Z for redo and stack cut.

After redo/undo if you type a character or remove one it will cut the stack to that index (won't be able to rewind what you already rewound before.)

* Moved the undo/redo detection to MixinGuiTextField#addToStack

* Added an override for if something goes wrong

see misc > "Enable text field tweaks"

Also removed the space that hannibal wanted gone. :)

* i hate files changed with only new lines
