Using the word "moodleoverflow" in students' UI is not awesome

While I understand the module name "moodleoverflow" is funny (at least to certain nerds population on the net), I think it would better to avoid using it in the actual students' UI - such as in the button label:

Not everybody gets the analogy with StackOverflow, but also the whole word "moodle" is not how some institutions call their LMS site even if it is built with moodle. I would recommend to re-use the standard Forum UI texts as much as possible.

The other related are texts like "This post is marked as solved by the teacher" - it is better not to refer to user roles like this. The module can be used in situations where there are no real "teachers" (think we decide to use it as a replacement for forums on moodle.org). It should be enough to shorten it to just "This post has been marked as solved"
