Expand role detection to support Blackboard's LTI implementation

I found that Blackboard prefers to send the Instructor role within the
"urn:lti:role:ims/lis/" URN. The support was already here, I just
extended the detected roles. Hooray for Blackboard support in
BigBlueButton!
Update bbb-lti README to note trailing slash issue

Save yourself hours of LTI debugging! Copying/pasting the URL bbb-conf
--salt brings along a trailing slash, which bbb-lti does NOT
appreciate. :)
