Better support for multiple swap partitions, avoids warning if swap is encrypted.
correct documentation on -s option

somewhere mentioned as --size, but the option is really just -s
fixes #100
sanitized the way key filenames are set

fixes #99
release documentation updates
fixed correct handling and deletion of keys when taken from stdin
fixes issue #74 for the new directory structure
documentation update for minor bugfix release
another fix to key handling

ultimately removing the case in which we guess if the key is near
the tomb: that is not anymore in documentation and we stop encouraging
to keep the key near the tomb.
