Unidentified Items Patch 1.0

unident.diff is a patch for Angband 2.9.2 which moves the names of most objects
to text files, in particular moving the names not described in u_info.txt
unidentified ones to a file called u_info.txt, and enables unidentified objects
to be edited within the % command.

It does have certain drawbacks:

There can only be one set of items which use the in-game scroll name generator,
and these will always be called 'an $item titled "$name"'.

The way in which the game interprets a primary index, in general, is hard-coded
as 0=always aware, 1-199=normal, 200=scroll-like, 201-255=always aware but with
a base item.

There always needs to be a base item to be included for each primary index even
if it is never used.

I have seen no evidence of bugs, and there is nothing in this patch which should
affect save files, but I can't be certain that it won't have any unidentended
consequences.

Any bug reports or other comments should be sent to me, Kieron Dunbar, at
