Title: HTML reprs for large dataframes.

As discussed in #4886, the HTML representation of DataFrames currently starts off as a table, but switches to the condensed info view if the table exceeds a certain size (by default, more than 60 rows or 20 columns). I've seen this confusing users, who think that they suddenly have a completely different kind of object, and don't understand why.

With these changes, the HTML repr always displays the table, but truncates it when it exceeds a certain size. It reuses the same options, `display.max_rows` and `display.max_columns`.
