add binary file name in new release option

[hyperion-cs]

Sometimes it is necessary to manually specify the name of the binary file in a new release (in which case, the target name and path will stay the same as for the "current" (old) executable). This PR implements this feature.

There are some breaking changes in the public API, so it's better to make a new minor version — v1.6.0.
