Alfresco Explorer is using URL Encoding when downloading a file

Alfresco Explorer is renaming the file using URL encoding when downloading the file.

This does not show in Alfresco Share or other protocols such as WebDAv.

I tested this issue in 4.1.6 and 4.2 and the problem is still there...it didn't happen in 4.1.3 so it seems to be a regression issue.

How to reproduce
----------------
Install Alfresco 4.1.4
Login to Alfresco Explorer
Create a file with name "Test File.txt"
Download the file

Expected results
----------------
The file downloads and the file name remains as "Test File.txt"

Actual results
--------------
The file downloaded has been renamed to "Test%2520File.txt"
