Add files for each search type. Extract config on clicking start

- Only allow adding files with appropriate file extension for each search type
  - e.g .org for org-mode search, directory for image search

- Extract file paths added to config and enablement state of each search type
  - This extracted state will be used to populate the khoj.yml config file
