printer: Add custom start/end G-code files

G-code is easier to read in separate files than in Slic3r configuration.

This G-code is based on the LulzBot Mini G-code provided by Aleph
Objects.  To increase speed, I added commands to set the hotend
temperature without waiting and arranged some commands like G28 and G1
to run while the hotend heats up.  For better clarity, I also added more
comments and blank lines and vertically aligned wiping command
arguments.
