Remove outdated reference from the manual
The manual description of detect item status references an extremely old version of ADOM
In the skills section of the manual, the description for detect item status includes the phrase:
"This skill is comparable to the automatic ability of priests (in versions of ADOM prior to 0.9.0) to discover the status of an item."
At this point, I think it's a safe bet that the number of people who played those old versions of ADOM but haven't played since is vanishingy small. As such, I suspect that this reference is now more likely to confuse than to enlighten, so it probably ought to be eliminated.
