Some fixes for dragonflight expension

[nulian]

Hey had to make some changes to make it work in dragonflight. Not done any wow lua stuff yet before so it's a bit messy.

Thought maybe you can use some of the changes to make the addon fully compatible in the future.

Issues found on beta

• Commented and removed some lines in Frame.xml of invalid fields according to wow.
• Disabled setLight because it gave some error about boolean not being able to iterate upon but couldn't find what changed that broke it.
• Disabled closeGossip calls don't seem to change working and it caused c errors
• Changed select gossip /active quest calls to get questID or gossipOptionID
• Disabled some gradiant stuff because that api has been removed and I didn't know how to do it otherwise

Here's how SetLight works now:

local lightValues = {
   omnidirectional = false,
   point = CreateVector3D(0, 0, 0),
   ambientIntensity = .7,
   ambientColor = CreateColor(1, 1, 1),
   diffuseIntensity = 0,
   diffuseColor = CreateColor(1, 1, 1)
};
local enabled = true;
self:SetLight(enabled, lightValues);

As for SetGradientAlpha, it's now SetGradient, with this signature:

-- old 
local orientation, minR, minG, minB, minA, maxR, maxG, maxB, maxA = ... -- old
texture:SetGradientAlpha(orientation, minR, minG, minB, minA, maxR, maxG, maxB, maxA)
-- new
local minColor = CreateColor(...)
local maxColor = CreateColor(select(5, ...))
texture:SetGradient(orientation, minColor, maxColor)

Ah found where the LightValues originated from used your settings as new values for it.

I did fix all the grandient alpha's.

It seems blizzard also broke the fallback for SelectGossipOption so I had to disable that line. The function seems to be found now but does nothing. --if SelectGossipOption then return SelectGossipOption(...) end

Tried to fix auto closing on things like flight master and the auto select of gossip skipping too much.

There is a new event for when player interaction windows closed which I hooked up to the event handler.
