Updated ajax search and entity selector usage to display and handle
items that the user does not have permission to interact with.
Started logic changes to not allow permission type to be passed around,
with views instead being the fixed sole permission.
- 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
