* template.h file cleanup
Reformatted the pre-macro comments as block comments.
Updated the ps2avrgb template comment to match the avr template's comment, which was more informative.
Deleted the line about the macro representing the Planck MIT layout, because the macro doesn't represent that layout anymore.
* base template keymap.c refactor
Deleted the deprecated TMK macro functions.
Defined two custom keycodes for use as macros by process_record_user.
process_record_user is now after the keymap and before matrix_init_user, where the deleted TMK functions were.
