Title: Adding file_exists because is_uploaded_file have problems with Windows

My case: using fs.grid, trying to upload some external file, the switch case always returns ``$method = 'storeBytes';`` regardless of the first case.

This was caused because Windows interprets paths in a really different way in comparation with Unix (http://faculty.cs.byu.edu/~jay/plt-doc/reference/windowspaths.html).
