Remove remaining legacy SFTP files that were missed
Running sync should not change exclude path configuration

Because Ruby uses shared string objects within a hash, leading
directory separators were being stripped from the exclude path
specifiers when processing symlinks. Now work with a copy of
each symlink path string to prevent this.
Explicit subjects should be defined within each method #describe

Class methods were running before each spec and within it because
the subject definition was at the top level.
Release v0.1.1.alpha

Hotfix to resolve issue with symlinks setting an incorrect rsync
exclude path.
