Subject: [PATCH] Updated the script build_all_shredos.sh so that if the
 defconfig is lite or extra then lite and plus-partitionare inserted into the
 filename immediately prior to the extension. The placing of this extra
 information at the end of the version information is important. In this
 position it doesn't interfere with the search that is conducted in the script
 find_shredos_boot_script.sh in relation to the search for the shredos boot
 disc. The sha1 checksum is calculated and placed in a file with the same name
 as the image but with the addition of the extension.sha1. These .sha1 files
 are also copied to the folder dist/ along with the corresponding .iso or .img
 file. The addition of this extra information in the filenames makes the files
 unique amongst the group of build files. This is required when the .iso and
 .img files are uploaded when a ShredOS release is published
