Fix Dark Steel Anvils in WAILA

[connor135246]

The WAILA integration for the Dark Steel Anvil didn't work if the "Sneaky Facades" option was on (which it is by default). The integration fixes the metadata used to display the block. With "Sneaky Facades" on, if you were looking at undamaged Dark Steel Anvils facing certain directions, they would display as Slightly Damaged or Very Damaged. Slightly Damaged and Very Damaged would always display as undamaged.

It was like this:

if (config("Sneaky Facades"))
{
  if (block instanceof Facade)
  {
    ...
  }
}
else if (block instanceof Dark Steel Anvil)
{
  ...
}

When it should be like this:

if (config("Sneaky Facades") && block instanceof Facade)
{
  ...
}
else if (block instanceof Dark Steel Anvil)
{
  ...
}
