- fix copy of any subdirectories under modules/ - adjust display of modules installation text to match the others - add support for custom user scripts (at /data/custom_boot_image_patch.sh - same as latest SuperSU zips) to automatically execute before reflashing the rebuilt boot image for bump, loki etc. modifications
