Support favorites

[shiqimei]

Background

Currently, BoardRecord has a property favorite labeings whether a board is favorited by a user, but this it not robust when we need to support multiple users later (a board is favorited by multiple users). We'd better use a new collection board_favorites to store such relationships.

Actions

1. remove favorite key from BoardRecord, and all related stuff;
2. add a new collection board_favorites, add a new file BoardFavoritesCollection in the models folder
3. define inteface BoardFavoriteRecord

   interface {
     userId: string
     boardId: string
   }

• when user starred a board, we add a new record to { userId, boardId } to board_favorites collection
• when user unstarred a board, we remove this record
• getFavoriteBoardsByUserId, is query { userId }

4. Services & Subscriptions

4.1. add following public methods for clients to call

public starBoard(boardId: string): Promise<void> // we get userId with Meteor.userId() on server
public cancelStarBoard(boardId: string): Promise<void>
public getMineFavoriteBoards(): Promise<IBoard[]> // get favorite board ids in `board_favorites` and query boards in `boards`

4.2 add BoardFavoritesSubscriber to subscribe changes to board_favorites

4.3 add global atom states to update state in favorites sidebar and top right bar
