Reverting pull request doxygen#537 until it will be fixed

Unfortunately code to support column/row spanning in markdown tables
breaking latex/pdf generation in case of utf8 symbols in table headers (at least)

Attempt to define USE_ORIGINAL_TABLES did not help, as important part of the code
was moved to the wrong place, so this patch reverts original tables code while
keeping span support in place for debugging/fixing. Just undefine USE_ORIGINAL_TABLES to
enable span support.
