... instead of full Bootmagic.

This commit changes the meaning of `BOOTMAGIC_ENABLE = yes` to mean "Enable Bootmagic Lite" instead of "Enable full Bootmagic" as previously meant.

This commit updates instances of `BOOTMAGIC_ENABLE = yes` to `BOOTMAGIC_ENABLE = full` to maintain the behavior that was specified by the rule.

Command:

`find keyboards/ layouts/ users/ -type f -name 'rules.mk' -exec sed -i -e 's;\(BOOTMAGIC_ENABLE[ \t]*=[ \t]*\)yes;\1full;g' {} +`
