initial thoughts on past events listing

Created by: flora8984461

Fix #6 (closed)

Have done: Implemented checkbox filtering and without filtering loading with calling apis with pages and paras.

TODO:

• Implement searchbar filtering with apis
• Implement past events together with upcoming

---------Update-2020-10-01-----------------------

• checkbox "Include past events" By default, show upcoming events, if include past events, after upcoming events finished loading, show past events

• greyscale past events, and also include a header as a separation that says: Past Events before we list all the past events.

• remove the Unknown "Event type"
