Remove technical event information

[johnsyweb]

Context

I hit #385 and thought that I should have a go at fixing it rather than simply raising an issue. There's no obvious way to determine whether an event is "live" without scraping, which parkrun do not like - this change assumes all events listed are live.

Change

Remove all references to technical event information and the wiki domain.

Considerations

I like red diffs and I cannot lie.

@johnsyweb, why did you add an event_has_started() function, instead of assuming everything was live? Did something not work if you started ripping out the if statements/parts that depending on checking if it was live?

[johnsyweb]

Good question. I didn't write the function, someone way smarter did. I simply refactored it to keep track of all the event_info.status == 'Live' || event_info.status == 'unknown' tests so that if I could find another way to determine whether an event was live, I could implement it once.

I don't think there's a way of doing this without hitting a whole bunch of pages (which is likely to result in firewall action), so this could probably be pulled out.

@fraz3alpha removing event_has_started() in e0cf2aa has no effect on the behaviour in either browser, so I think this is good to go.

All seems very reasonable, so I have merged it - thanks a lot!
