Simple enough I think....

Dimension blacklisting.

Mainly for the runic dungeons, witchery and thaumcraft dimensions.

blacklisting for what?

What should blacklisted? The crafting of Ender IO machines, their placing or their operation? And why?

For the staff of travelling. Sorry for the derp of not specifying that. Oops.

You can black list blocks which should not be teleported through

The blocks themself? Ah, must of missed that. Only saw the ability for air or not air.

lines 513 and 516 (notepade++)

If travelStaffBlinkThroughSolidBlocksEnabled is set to false and this is true: the travel staff can only be used to blink through transparent or partial blocks (e.g. torches). If both are false: only air blocks may be teleported through.

B:travelStaffBlinkThroughClearBlocksEnabled=false

Allows the travel staff to blink through unbreakable blocks such as warded blocks and bedrock.

B:travelStaffBlinkThroughUnbreakableBlocksEnabled=false

then at the bottom

line 1013 (notepade++)* werid this seems to be wording wrong. But setting it to false makes it not possible to pass through the blocks.

If set to false: the travel staff can be used to blink through any block.

B:travelStaffBlinkThroughSolidBlocksEnabled=false

Sorry for the formating my phone is stupid.
