David Jilke d489444119 Complete Plugin Keymaps for Creative Zen X-Fi3 
This patch completes the plugin keymaps for the Zen X-Fi3 and enables those plugins for compilation.
One key was changed in "button-target.h" for compatibility with Rockboy.
This also caused the changes to "keymap-zenxfi3.c", to keep the stock functionality (no further changes in here).
