Max/Pd externals, example texts

-modified mage.cpp/h and vocoder.cpp/h to add vibrato function used in Max and Pd externals. The modificatio in fft-sptk.h is just a blank line, sorry for that.
-reorganized codes in mage~.cpp for Pd and Max external so that they are more easy to compare
-added functions to those : labelnextvowel, labelfilluntilend, vibrato
-added tutorial and helpfile for Pd and Max
-example texts in zip archive : example_processed_texts.zip
-compiled Pd and Max externals which should work on OSX 10.6.8
