[Freeciv-Dev] Inca -> Incan (PR#147)

[Matthew Hunt <mph@xxxxxxxxxxxxxxxxx>]

All nations except the Incas have an adjective form of their name in
the "name" field of nations.ruleset.

This patch changes "Inca" to "Incan" to match all of the other nations.

(http://www.m-w.com/ says "Inca" is the noun and "Incan" is the
adjective.)
