ncmpcpp: Re-enable auto-fetching of lyrics

As of ncmpcpp 0.6, lyric downloads work again
ncmpcpp: Spectrum visualizer fixed in 0.6_beta3
i3: Enable notifications for ponymix keybinds
brightness: Add 'max' option
bash: Turn search into a function

This makes the $(pwd) call work as intended, also helps to
make the command easy to use (just type "search <something>",
no wildcards needed)
