Added support for mulit-line endpoint descriptions via blank
intermediate lines in php controller method docblocks.
Also tweaks endpoint header design for better flexing and alignment.
Is a little awkward, emulates a 'list' API endpoint but has unstable
paging and does not support filters/sort. This is detailed on the
endpoint though.
Made some updates to the docs system to better support parameters
and examples on GET requests.
Includes tests to cover.
For #909
- Primarily moved and re-organised view files.
- Included readme within views to document the convention.
- Fixed some issues with page field select list in previous commit.
- Tweaked some route names while going through.
- Split some views out further.
Closes#2805
