add obfuscate to instant color filter

[yusef88]

it makes sense to include it under blackout filter

it's a bit like asking, "add a new font to this real-life book with a physical existence"
because obfuscate is a scripting command.

However, the idea does make sense, that blackout filter and obfuscate belong in the same place.
