Removing library file from beets
Creating an entire-textobject

Its annoying to always need "ggVG" to select the entire file-content. So
I firstly mapped a shortcut. With vaa/via was it possible to
visual-select the entire file-content. Much better is the possiblity to
use an custom text-object from the textobj-user plugin from kana.

- Deleting the crappy vaa/via shortcut to visual select the entire
  document.
- Installing the textobj-user plugin.
- Creating a section for custom textobjects in the plugin.vim file
- Because I am lazy: Copy & Pasting the entire-textobject from kana.
