Escape with double quotes instead of single quotes

Fix maybe #138?

This takes us away from the standard shlex implementation. It is still not what you want on Windows (backslashes will not be understood), however it should do what you want in more situations (for example it supports spaces).

@vtyw if you could please test this version against your Windows server, I'd appreciate it :)

I can confirm that it works with spaces e.g., scp.get('V:/sample 1.txt'). Are there any other characters you'd like me to test?

Thank you so much!

I think quotes are outright forbidden in Windows paths. Maybe $ % ^ ?

There is an inconsistency in the naming of the file if you don't specify local_path:

• scp.get('V:/sample 1.txt') => 'sample 1.txt' (single quotes in the filename)
• scp.get("V:/s$.txt") => scp.SCPException: scp: V:/s/$.txt: No such file or directory
• scp.get("V:/s^.txt") => 's^.txt' (single quotes in filename)
• scp.get("V:/s%.txt") => s%.txt(no quotes in filename)
