Release 10.2.1

[crc]

Alexander Shendi reported a bug in 'nip' to me today; I've pushed out
a new (10.2.1) release that fixes this.

Specifically, in 10.2, the primitives have a '.inline' class. 'nip'
was assigned this class, but as it is not a primitive, only the first
part of the definition was being compiled into words that used it. In
10.2.1, it has the proper '.word' class assigned.

This bug does *not* occur in the development branch, so those using
the development snapshots should have no problems from this.

If you are using 10.2, you can grab the update at
