Linked Series (#1230)

* Implemented the ability to link different series together through Edit Series. CSS pending.

* Fixed up the css for related cards to show the relation

* Working on making all tabs in edit seris modal save in one go. Taking a break.

* Some fixes for Robbie to help with styling on

* Linked series pill, center library

* Centering library detail and related pill spacing

- Library detail cards are now centered if total number of items is > 6 or if mobile.
- Added ability to determine if mobile (viewport width <= 480px
- Fixed related card spacing
- Fixed related card pill spacing

* Updating relation form spacing

* Fixed a bug in card detail layout when there is no pagination, we create one in a way that all items render at once.

* Only auto-close side nav on phones, not tablets

* Fixed a bug where we had flipped state on sideNavCollapsed$

* Cleaned up some misleading comments

* Implemented RBS back in and now  if you have a relationship besides prequel/sequel, the target series will show a link back to it's parent.

* Added Parentto pipe

* Missed a relationship type
