[crossfire] Auto ID on examine

[Brendan Lally]

Hello all,

Just wanted to get some opinions on the following patch:
https://sourceforge.net/tracker/?func=detail&aid=2988536&group_id=13833&atid=313833

This changes the way the examine command (triggered by left
clicking on an object) works so that if the object is unidentified,
and the player has the appropriate skill, then an attempt to identify
the object is automatically made.

The intention is that this should make the ID process much smoother for
new players, and less likely to be discovered after wasting money on ID
tables or selling items that were useful.
