username and email request for lti module

allow username and email can be passed to a lti third party app
ask user permission when lti button is clicked
allow course editor to customize text on lti launch button
I think the string should make it clear what the default is, so they're not left wondering what happens if they don't provide button text.

"Allows you to override the default text ('View resource in a new window') on the button used to launch a third party app."

I actually can't find the "View resource in a new window" text, could you point me at that? I want to make sure that the prhase and capitalization is exactly the same.
