We made some changes to keep the rules engine running smoothly.

• Fix: imageSVGHasRole now ignores svg elements if they are not in the accessibility tree.
• Fix: imageActiveSVGHasLabel now ignores svg elements with role only and no tabindex.
• Fix: pageCanBeZoomed to exclude user-scalable values between -1 and 1.
• Change: accessKeyUsedMultipleTimes is recategorized as an Alert.
