- Updated tinymce to latest 4x version.
- Most elements done, but still need to do editors, tables and final

Optionally we could consider removing the rule at line 274. This doesn't handle multiple layers of nested lists and would be better covered by the generic rule which checks for an `ol` or `ul` nested inside a `li` which is how MarkDown renders nested lists as HTML.
- Removed different PDF template used on pages.
- Updated export view files to have the intended format passed.
- Shared the export CSS amoung the export templates.
Should hopefully address #1886

- Set default color to use app primary color, to help them blend into
the design a little.
