Scroll-less chat windows for tabbed chat

[taco-man]

Exactly what it says it is
The New chat window that has tabs, but without the scrollbar for the text.

In the previous version the Shift Page-up/Shift Page-Down was not working properly. This has been addressed and should now ,as the devs say, "Work as intended".

SOE decided it would be smart to make it impossible to change the background opacity with the slider for the chat window, this has been fixed and you can now adjust the background opacity for them.
