Harvey Tindall f4f18d41ea Modularized JSON storage
user_template and other files are now accessed via JSONStorage, which
has dictionary like attributes for each file which can be used like a
dictionary, without the need to manually read and write the file. This
was done so that other storage types (e.g a database) can be added in
future.
