This is a follow-up commit to "Update <provides> info in pkg runtimes",
which adapts the users of the wm pkg to the changed label of the "focus"
nitpicker session.
The component is no longer loads from '/test.pdf', the first PDF file
found in the root directory of the file-system is loaded automatically.
The behavior cannot be overridden by configuration.
Feed MuPDF with characters from input events to MuPDF rather than
translate raw key codes to ASCII. This enables almost all MuPDF key
bindings without the need to maintain a lookup table. Mouse navigation
has been enabled as well. To print the key-bindings to log, press '?'.
