Reenable the usage of "manifest" and "collection" param at URL

AC:

• When accessing TIDO in zero-config mode, users can append a "collection" or a "manifest" GET parameter with the respective URL as value like: zero-config.html?collection=https://example.com
• The recently introduced tido GET parameter with all the other TIDO settings should stay next to "collection" and "manifest" params
• m could/should be ignored when "manifest" is given
• if only "collection" is given m should still be considered
• URL should always trump config
