Want to Read List (#1392)

* Implemented a Want To Read list of series for all users, as a way to keep track of what you want to read.

When canceling a bulk action, like Add to Reading list, the selected cards wont de-select.

* Hooked up Remove from Want to Read

* When making bulk selection, allow the user to click on anywhere on the card

* Added no series messaging

* Code cleanup
