The Get/Set config plugin functions were hardly used in ESPEasy.
Currently the `config` command is only implemented for the "Level" plugin, but hardly documented.
Its counterpart, to Get config, is also hardly used, but can be very useful to access values (either settings or unused values) via `[taskname#valuename]` notation.
This is now also added for the many GPS values, as one can only set 4 units of measure as task values.
Oversampling does average all readings between 2 calls of `PLUGIN_READ`.
N.B. if the sensor is put to sleep, any collected samples will be flushed by scheduling a `PLUGIN_READ`.
When waking up, any stored data in the averaging buffer is flushed.
Split the plugin related substitutions into separate files (per 10) to speed-up building docs.
Please note the use of indirect paths used in includes, needed to link those replacements from other directories.
