Optimised permission fetching so that it won't initialise a bunch
of models for the role permissions and instead does a manual
query to get the data directly.
- Created new dropzone component.
- Added standard component event system using custom DOM events.
- Added tabs component.
- Added ajax-delete-row component.
- Moved Code-editor from vue to component.
- Updated popup code so it background click only hides if the click
originated on the same background. Clicks within the popup will no
longer cause it to hide.
- Added session-level history tracking to code editor.
- MDN theme appeared fairly bad for markdown use, and the geometric
background was a bit much. Swapped out to default theme.
- Rough-added stickiness to docs sidebar, will need more work once it
starts to expand possible screen height.
