Fix for incorrect ignore attributes pattern

[wclr]

var ignoreAttributesRegExp = /dataViewId|class|id/i

matches all words that contain id/class letters, not the whole words

/^(dataViewId|class|id)$/i 

fixes things.

This change is included in #701. I moved it to that pull request because I wrote a test to verify the change. Thanks for the patch!

One more thing "i" modifier is exessive there. And look at this issue #695 I had to add more in pattern to overcome it.
