Doug Coleman 9f213f96f6 core: Add the shuffler words but without primitives. 
The nipd branch slowed bootstrap by a minute, this patch does not.

sorry about changing the fjsc line endings...

Björn Lindqvist 6f10f06c27 hash-sets,hashtables: make it so the array backing the hash is non-empty 
Commit 70c7f9e029 made it so the code
assumes the array is not empty. But it can be empty if the hashtable is
created using "hashtable new" and then it can crash because it reads
uninitialized memory. Setting the initial of the array slot to
a valid hash-array should fix that.

Björn Lindqvist 70c7f9e029 hash-sets,hashtables: improved key@ word 
Don't need to check the length of the backing array because it can be
assumed to be > 0. That should make hash lookups a little faster.
