Modified zip implementation to preserve filenames of single file resources.

Browse Source 
Also modified the directory structure of single file resources to make them consistent with multi file resources.

For multi file resources, the original folder is renamed to "data", resulting in a layout such as:
data/file1.txt
data/file2.txt
data/dir1/file3.txt

For single file resources, the file is now moved into a "data" folder, like so:
data/file.txt

This is slightly unconventional, but is appropriate within the context of QDN to keep everything consistent.
