Corrected glitch for signing dialog, when multiple file signing is required.
yubisigner v0.1.3 binaries are signed with yubisigner
.sig files are time stamped with opentimestamps.org
The yubisigner signing certificate .pdf and accompanying .ots time stamp should proof
in an easy way that I am the author of the signed software releases.
For additional security of the source code, merkle-tree.txt in the repository is signed too with yubisigner and additionally time stamped.
