Revert "remove-duplicates: compare ALL files, don't care about subdirs"

This reverts commit 864d5fac6c27b7497e020b4baccd0c5d578a3ebb.
(turned out that subdirs are actually useful - for initial sorting)

remove-duplicates: display number of files to compare
remove-duplicates: change variable names
remove-duplicates: complete rewrite. only compare files with same size
remove duplicates: don't remove hidden files by default. add dry-run.
remove duplicates: check if one filename is a substring of another

so that in case of foo.txt and foo(copy).txt
the script will remove foo(copy).txt

remove duplicates: improve description
Update remove-duplicated-files.sh
remove duplicates: don't create dupdir if in dry-run
remove duplicates: not only empty files, but other files up to 5b
