Tables: Improvements (#530)

Tables now handle escaped pipes when testing, in table borders, and in
the inline content.  To achieve properly, a bug had to be fixed related
to appending escaped chars to the Markdown class.  Now appended chars
only appear in the current instance.  Lastly the first backtick in a
table can be escaped rounding out the last corner case.
