Version 0.4.17

Includes

• GCC 5.3.1 warnings fixes from Jaromír Mikeš and Javier Serrano Polo
• Avoid global namespace symbol conflicts and possible double free from colin-m-fletcher

I've checked that it compiles, but don't have an easy way to test the plugins are built correctly.

v0.4.16

Lots of patches from other people.

New vocoder plugin, crossported from LMMS from Javier Serrano Polo.
Improvements to the build system (it's still somewhat archaic though) from Tres Finocchiaro and others.
Lots of documentation translations and typo corrections from Olivier Humbert.
Gettext improvements from Sebastian Pipping.
