Use sha256 for package checksums
* packages/download.sh: Use sha256sum * packages/packages.current: Converted to sha256 checksums.
Conversion was done on a valid download folder where all sha1sums
matched by the command:
for file in $(ls *.tar* *.zip); do
SHA1=$(sha1sum $file | awk '{print $1}')
SHA2=$(sha256sum $file | awk '{print $1}')
sed -i "s/$SHA1/$SHA2/" packages.currentdone
