This allows fabric to test if a file exists via symlink since a standard exists will not return the proper result.
Makes useful addition to test if a remote directory is a symlink or not, helps expand on "exists" method to give a broader scope for checking files and paths.
The "e" flag does not apply to links soft or hard.
Thanks! I'm a moron and this should've been on master after all; thankfully it's trivial to go from stable => dev, so I simply merged master into my integration branch :)
Also made some tweaks & added tests + changelog (vs asking you to to so) since I felt bad for punting your tickets around ;)
