Increase tex2lyx output format to 334.

331:     Set the caption flag for longtable caption rows
332:     Nothing to do (empty lyx2lyx conversion)
333:     Nothing to do (tex2lyx did already use the new style names because it
         uses the current layout files)
334:     Nothing to do (tex2lyx did already produce the new format, since it
         used the LaTeX paper names also in the output and did not suffer from
	 bug 4868)
