Small fix for multiple achievement awarding bug (story: was confused why the "verify membership" achievement was only coming up once as it was confusing people, especially as we'd written working code for displaying stuff like "achieved on x (and two more times)" - turns out the verify membership achievement was being updated with the new time rather than extra copies being created... whoops)
Overhaul to newsletter editor:
Side by side preview on Create and Update pages!
Pseudolive preview (updates automatically after 600ms of not typing)
Buttons specifically for newsletter headings (H2 with custom class, H3 with custom class)
Buttons specifically for newsletter images (image at 50% width on left, image at 50% width on right)
Section break button (better icon ideas accepted, creates a clearfix on a new line)
Custom class button (better icon ideas accepted, creates {.custom-class-here} at end of line
{.custom-class-here}
at end of lineFixes #216
