More natural language for 'mode'

Suggestion from Sandy, as no one really knows what 'get mode' is.
More of a call to action on friends intro

Based on suggestions from Sandy.
Changed wording of getting access

On suggestion of @skivvies did 'users online getting access' instead of 'users getting access online'.
Forgot the word 'access'
Changes suggested by pants

Lower case G on grow, and countless instead of thousands. 

Also added newlines, though I don't have a build so am not sure how it'll look / if there's enough space.
Less 'mode' references, replace 'pc' with user

Just completing the dropping of 'give mode' in favor of 'Giving Access'

And got rid of PC language, in favor of user.
Attempt for more clear language in adding sites.
Added note about logging in to google

A user expressed concern that this looks like a phishing page, and the experience is a bit weird as Lantern is a desktop program, not a website. So put some language in to assure users their passwords aren't stored.
