[droidknights#259, 위젯 기능 추가]

[작업내용]
  - Glance Library 추가 (targetSDK 버전 제한으로 beta01 버전 적용)
  - 북마크된 세션 표시 위젯 기능 개발
    - 타이틀 클릭 시 앱 실행
    - 앱 내 세션 북마크 추가 시 위젯에 리스트 업데이트 하도록 구현
    - 위젯에서 세션 클릭 시 앱 - 해당 세션 상세 정보 화면 이동
    - 세션 카드 - 타이틀, 시작 ~ 종료 시간, 발표자 표시

[TODO]
  - 발표자가 2인 이상일 경우 이름 표시할 수 있도록 로직 수정 (현재 발표자가 2인 이상인 경우 없음)
  - 위젯 내 북마크 해제 버튼 추가
