Make rsod less annoying

[pmario]

There are some good argument in this discussion, to make the js error form more user friendly.

• I did reorganize the CSS a bit.
• centering the form is easier now.
• form is max 80% high
• error-message has overflow auto, so scroll bars will be used if needed.
• error-message text got its own class name.
• did remove the text shadow, since it creates very hard to read text

I agree! This is a more sophisticated implementation than my own personal hack.

For reference this is what it looks like in Chrome:

the advantage can be seen if you have a lot of text. The cancel button will not be moved out of view. Which actually was the reason, for me, to make the PR,

@pmario Updated the screenshot with more text.

While we are at it any chance we could change the color of the button text? White on white looks bad. Glad there is only one button!

@Jermolene - could this be added to 5.1.17?
