config: Add printer config for the Ender 3 by Creality3D

- Changed max positions
- Tuned PIDs for my stock Ender 3 heaters (using 200/50)
- Added the serial device as 'by-id'. Not sure if that is working as I
expect it :)
- I did set the position endstop to 0.5 .. Not sure if people like that.

+# This file contains common pin mappings for the 2018 Creality
+# Ender 3. To use this config, the firmware should be compiled for the
+# AVR atmega1284p.
+
+# Note, a number of Melzi boards are shipped without a bootloader. In
+# that case, an external programmer will be needed to flash a
+# bootloader to the board (for example, see
+# http://www.instructables.com/id/Flashing-a-Bootloader-to-the-CR-10/
+# ). Once that is done, one should be able to use the standard "make
+# flash" command to flash Klipper.
+
+# See the example.cfg file for a description of available parameters.
