Up to [LON-CAPA] / loncom / interface

Adds check before calling lonfeedback::newline_to_br to see if
the text contains block-level HTML elements (such as <table> or <p> or <br />).
If HTML is detected, newlines will no longer be automatically converted
to <br /> tags -- this resolves bugs such as 5550, where for
example, inserting a table using the WYSIWYG editor causes
erroneous break tags to be created.
