Subject: This adds a 60 second screen timeout for TWRP. Might consider making
 this configurable in the future. Will also set overlay to lockscreen so we
 don't have inadvetent screen selections. Touching the screen will bring the
 display back up. add back check script for poweroff move diff time function
 to twrp-functions.cpp make sure we chmod after copy_file add read_file and
 write_file functions to twrp-functions.cpp make single thread try to force
 update screen add forceRender drop caches after tar processing
