Add functions to generate sample data for various formats
* Zotero Web API JSON (Zotero.Item::toJSON)
* CiteProc-JS JSON
* Export translator JSON
* Direct serialization of Zotero.Item fields
Add a way to load sample data into DB from JSON
Add tests for loading sample data into DB
Add tests for automatically generated data
This will help us make sure that field mappings and data formats don't change
Don't echo version on Windows, because it hangs Firefox
Also add testing with Firefox Beta (and prior ESR, but commented out for now, since we don't support it and we know it breaks)
Implements the beginnings of unit testing infrastructure using
mocha/chai. The unit tests can be run locally using test/runtests.sh,
although this will need tweaks to run on Windows. They should also run
on commit using Travis-CI.
The unit tests themselves live in test/tests. The index.js file
specifies separate test sets, which can be run individually by calling
test/runtests.sh <testsets>. Right now there is only a single unit
test, but hopefully we'll have more soon...
