[Kde-games-devel] Valgring Uninitialised value error in KTron

[legolas at legolasweb.nl]

Hello,

This problem is now solved, with help of Albert Astals Cid.

These errors occured, because KGameDifficulty::init() was called later
than the first usage of it. This happened because there was a call
(loadSettings()) within the constructor in Tron, which was constructed
before the KGameDifficulty initialization and used KGameDifficulty.

I've moved the loadSettings to the end of the KTron constructor, which
fixed the problem.
