Static code analyzer test

Hi there!
after read this article hownot2code.com/2016/08/25/long … /#more-977
I just curious about same typos and issues in Urho3d project.
and I find few issue or mb typos

for example this:

autoLoadPaths[0]
mb this need to fix to autoLoadPaths[i]? because it in for-loop

also you may download this plugin( viva64.com/us/pvs-studio/ ) and may see another typos and some troubles in code

add:
matrix2.h have float m02_ but no used anywhere anymore

In the autoloadpath example the intention is to compare the first element.

But thanks for the matrix2 unused variable spotting.
