Modding away the obnoxious ghost block fade

[JDStrawesome]

Now that we have this phantom block cursor effect while building, I find the fade time to be obnoxious. Especially because I use a lot of specialized and decorative blocks in my builds and I use them in extended rotations. So I spend a lot of time just waiting for the block to appear as I move the placement from space to space. I know a second or so seems insignificant, but when you are rotating and placing hundreds of blocks, these small pauses add up.

Is this timer controlled in the xml files? I have done some automated searching and haven't been able to find any clues.
