Put crashes if destination already exists as a folder.

[edev]

How to reproduce:

1. Create a local file named foo
2. Create a remote folder named foo
3. Run put foo from the client

Output:

sftp> put main.py
Failure
[dylan@localhost git]$ 

Cause:

In the put action, we catch only FileNotFoundError. This is a subclass of OSError, but we don't catch any other subclasses that might arise, nor the parent class itself.

Solution:

Either (a) add an OSError handler after the FileNotFoundError handler or (b) if the OSError messages are clear enough, replace the FileNotFoundError handler with an OSError handler that looks something like:

except OSError as e:
print("Error:", e.strerror)

This is no longer an issue, yes? Can we close this?

EDIT
Oh, I see. This is for pysftp to know about maybe someday. Nevermind.

Huh? Nope, you may be right, we may be able to close it. I hadn't updated our issues today.
