Fix test_servlet_newrequest

NewRequestServletTest.test_newrequest did not use valid post data
for new requests resulting in a default request. Fixed post data and
add additional tests for the new request.
Restrict verify to pushmaster and user
Add TemplateTestCase

TemplateTestCase provides the bare minimum needed to test
templates through rendering.
Add test_template_request

New template test file for templates/request and related templates.
Add initial test for verify button
	Button should only be visible to requester and pushmaster
