Ticket #0001664

Summary	Rename the issue! datatype
Description	Given the recent changes in semantics of this datatype, I do think it is no longer appropriate to stick to the current name. Especially in the light of the behaviour described in #1663, this could be a significant source of confusion for programmers coming from R2. This source of confusion is a totally unnecessary one, which we can easily get rid of by renaming the datatype to something more appropriate. The new name should probably indicate that this datatype is a member of the any-word! family by sticking to the *-word! convention.

Other options would be "hash-word!" or "hex-word!". Given that the #-sign is also referred to as octothorpe, we could also go with "oct-word!". "pre-word!" would be another option hinting at the use in preprocessors or dialects.
