This patch enables to change the default configuration value for outputs and
pointer by defining a configuration for "*". Values defined in this object
override unconfigured values.
This patch introduces more configuration options for pointer devices:
* adds `tap` option
* adds `tap-drag` option
* adds `tap-drag-lock` option
* adds `natural-scrolling` option
* adds `no-scroll` to `scroll-method`
This also changes the way unconfigured options are handled. `hikari` is no
longer going to overwrite unconfigured values with its own default but rather
keeps them unchanged.
