Feature request: Handle drag & drop of .xlsx

Dear KNIMErs,


Quick feature request: please handle drag & drop of .xlsx -- it works with (outdated) .xls!





P.S.: Bizarrely, renaming an xlsx to xls works without complaints in KNIME, while Excel first alerts about the format mismatch, but then opens it as well.


P.P.S.: Many times this renaming thing is still faster than clicking through to the appropriate location after manually adding an XLS reader node - even when renaming back and re-adjusting the XLS reader's path. By the way, maybe it should be renamed to XLS(X) Reader node? :)

Oh, and handling PDFs and DOC(x)s via drag & drop (if text processing is installed) would be nice, too.
