v1.3.0

Features:
- Hidden links are now clickable/selectable/deletable in the same way normal links are.
- Added saved configuration for generating canned data from PandA simulator
- Minor style tweaks

Fixes:
- Errors from malcolm regarding the layout attribute no longer overwrite the subscription ID and cause a crash.
- Orphaned attributes now get hidden as soon as the block meta is updated to orphan them (n.b. this bug still exists for orphaned group expanders).

- Navigating to a layout via the nav bar now fires the necessary subscription requests.
- Highlighting text and dragging & dropping onto the layout no longer causes a crash.
