[7.x.x] Fix the storage of OpenDocument files and Office Open XML files

[adamretter]

Previously OpenDocument files, and Office Open XML files were mapped onto XML Storage, however these are not XML files, they are actually Zip files (containing XML files). We now correctly map them onto Binary Storage.
Closes #189
