Issue description:

Refined Storage cable blocks (and possibly other blocks in RS?) don't override Block#allowsMovement(). Specifically, this method is intended to determine whether or not an entity can pathfind through the block; the default for land-based and flying entities is to allow pathfinding if the block doesn't have an opaque collision shape. Unfortunately, because RS cable blocks have a movement-blocking collision box, entities will get stuck (forever) when trying to pathfind through them.

What happens:

Entities will attempt to pathfind through RS cables even though they can't move through them.

What you expected to happen:

Entities should know to path around or over these blocks.

Steps to reproduce:

See screenshot below

1. Create a 3x3 ring "fence" of cables
2. Put a cow in the middle of it
3. Hold some wheat. Cow should step/hop over the cable to get to you, but instead tries to path through the cable and gets stuck.

This is easy to fix: simply override allowsMovement() to return false in those blocks of yours which are not a full cube, but do have a movement-blocking collision shape. You will notice that vanilla does this for many of its blocks.

Version (make sure you are on the latest version before reporting):

Does this issue occur on a server? [yes/no] yes

Note: the reason I'm reporting this is PneumaticCraft drones easily get stuck on RS cables. And you're far from the only mod author to miss overriding allowsMovement() - it's an easy one to miss and the effects are subtle with most entities, but PNC drones love to find these problems :)
