addStudy updated to support field modifications, search now gets from DB and eligibility can be parsed as JSON

JSON.parse(data.eligibility)  will now return a JSON object.  To use,
when adding a study, the string must be in the format of:

{ "elig1": "value", "elig2":"value" }

That simple and it is tested
Added PHP for getDataFromDB

Usage URL
getdatadb.php?type=studies[&startDate=date][&endDate=date][&keyword=word]

last three params are optional.  Search will by default return all
current and future effective studies
Added addstudy.php

This will insert a new study into the DB
Updates for new PHP files and fields

Modified addStudyTest, addStudy, and search to use new fields
Added SQL file for reference(can be copy pasted into the MySQL server)
