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.
- Updated editor, and other area, styles to look okay in dark mode.
- Used tinyMCE theme generator to create dark mode theme.
- Updated tinymce to latest 4x version.
- Most elements done, but still need to do editors, tables and final
pass.
- Toggled only by quick js check at the moment, checking via css media
query. Need to make into user-preference toggle.
