Removed out-of-date batch scripts.
TDS-10 Add proper date/time support for symptoms and events

Have added a proper date for symptoms and events, but have not added proper date/time support in the symptom pages.
TDS-8: Add separate API for mobile devices

Added new pages for symptoms and events separately.  Web pages work, but JSON not working correctly yet because cookies are not being passed back to the client at all (certainly not when logging in, which is the first place it should happen).
TDS-11 Fix cookie handling for mobile JSON API

Cookies are now working.  Had forgotten to set the session when returning JSON results; was only set for HTML results.
TDS-8: Add separate API for mobile devices

Have added GET API for mobile devices, but have not yet added PUT API for uploading new symptoms or events.
