Update rsync.js with Windows support

* Update rsync.js with Windows support

Add a new function: escapeDirectorySeparator() which used in escapeFileArg() to set directory separator correctly under Windows.
If you use th cygwin's rsync with OpenSSH for Windows (http://www.mls-software.com/opensshd.html) they are using standard linux directory separator and this update can handle directories under Window.
To use rsync under Windows, you need to symlink your directories well (with standard Windows mklink command line tool).

* Update rsync.js

Copied contents of the escapeDirectorySeparator function under escapeFileArg and remove unused function.

* Update input.test.js

Add "should convert windows path under windows" for source and "should convert widows path for destination" for destination test.

* Update input.test.js

Set platform to win32 with safe.

* Update input.test.js

#sourcewin32 and #destinationwin32

* Create inputwin32.test.js

Windows input source and destinatiion testing

* Update input.test.js

Move windows test to inputwin32.test.js

* Update inputwin32.test.js

update to mocha before and after (not beforeAll anf afterAll)

* Update inputwin32.test.js
