Random modifications one - from Phase II meeting

Heya, so knocked off some of the simpler stuff on list first.  But these are some sweeping changes (though in most cases trivial as many (especially in static pages) were for code and appearance consistency) so would be great to merge as soon as possible.

* Remove blue dot
* Add google maps links to upcoming event boxes
* Make "not finding an event" less emphasized
* Indent answers on Q&A pages (students, teachers, donors)
* Fix the line spacing on the the lists

CSS wise removed some unused styles and replaced .spaced-help-content with .indented-content as will use site wide.

Also add a teacher_advice page so the teacher faq wasn't so monolithic, we can rearrange into something else later for sure but for now think is alright and improvement.
