Small fixes

[krajzeg]

Hey,

Two unrelated fixes in this PR (not the best practice, I know).

The important one is something I found while checking out the source code to learn how the game works - the "analyze level" of an ICE was not taken into account at all when determining its GetEffectiveRating(), due to a stray "this":

	if (this.bIncludeAnalyze)
		nRating -= this.m_nAnalyzed;

This makes analyze completely useless without the fix.

The other is a small fix for issue #1, enabling the scan button in COP nodes.

...Are you sure these fixes are what Shawn Overcash intended?

@TideGear This has been years ago now, but I'm pretty sure the analyze bug is a bug in the port. I'm not sure how/if scanning COP nodes worked in the original.
In any case, won't be filing a PR, but feel free to use/not use these one-line changes in your fork - which is a cool idea, would be nice to be able to play Decker on a phone! 👍
