Title: Add support for channel ticks to castbar.

Largely inspired by oUF/mono and Gnosis.

Tested in Tukui with Penance (ticks immediately on cast) and Soothing Mist (does not tick immediately) using):
```Lua
CastBar.Ticks = {}
for k = 0, oUF.MAX_TICK_LINES - 1 do
Tick = CastBar:CreateTexture(nil, 'OVERLAY')
Tick:SetTexture(CastTexture)
Tick:SetVertexColor(0.8, 0.6, 0.6, 0.4)
Tick:SetSize(2, CastBar:GetHeight())
CastBar.Ticks[k] = Tick
end
```
In addition to using as directed in the "Examples" comment section.
