LibGUI: Consider carriage returns when counting lines in a label

Browse Source 
We create labels in the Browser from text on web documents, which may
use carriage returns. LibGfx will split lines on CR already, but LibGUI
would not consider CRs when computing the height of the containing
widget. The result was text that would not fit in the label's box.
