- ES6ify (now using class syntax to define QAItem objects)
- Fix bug with KeepRight marker rendering not updating properly
- Use `qa-` prefix for the UI element classes to differentiate from iD
validation error related UI element classes
- Move away from "error" where possible in source
- Move away from snake_case naming where possible
Note that some function/method names have been untouched to make life
easier for v3 development. Have added note comments where appropriate.
Use of MouseEnter and MouseLeave is nicer for SVGs since it won't fire
multiple times (shouldn't happen hear anyway as only one element).
Triggering redraw after forcing related elements visible causes them to
render without having to pan manually.
I've converted the improveOSM errors to use this new generic QA error
structure which should allow for more general code to be used in
behaviour and UI.
Sidebar preview is currently broken, but will be fixed shortly.
