Subject: refactor: extract assets into their own database table. #215 (#220)

* Allow downloading more content from a webpage and index it #215
added a new table that contains the information about assets for link bookmarks
created migration code that transfers the existing data into the new table

* Allow downloading more content from a webpage and index it #215
removed the old asset columns from the database
updated the UI to use the data from the linkBookmarkAssets array

* generalize the assets table to not be linked in particular to links

* fix migrations post merge

* fix missing asset ids in the getBookmarks call
