Adding keywords for Sunflower testing; Fixing Independent test running

1. Adding two new keywords - Register New User, Create A New Entry
2. Modifying keyword -Open browser to login page to accommodate all templates, Login to Eden with Arguments
3. Fixing the Independent test running aspect
3.1 Login, Logout removed from Start Testing and End Testing as the Login/Logout should depend on the use case.
3.2 Added Login, Logout to every testcase
3.3 Suite Setup, Suite Teardown added to every testsuite
3.4 Removed the unnecessary __init__.txt
This should check whether already logged in, and only login if not otherwise skip. One logout after the end of all tests in this run (tearDown), or otherwise if explicitly requested by the test. Repeated logins make testing very slow, and don't add any value.
