Add ability to get randomized first word as room setting

[mayo320]

Before game starts, add a toggle to generate random first word (so that users don't get to pick their first word).

Not a bad idea. I probably wouldn't do this with a toggle, but instead let players individually autofill their first word with random words.

Considering the static nature of the web app, it's probably best to make a get request to something like https://random-word-api.herokuapp.com.

If implemented this way, this change is local to the StartComponent (probably? I haven't touched this code in a while). This would be a good first issue.

Oh, if it were a room setting, you'd be able to generate longer "chains" because words are first seen by the people who draw them, not the people who picked them.

If you want this instead, please open a second issue. It's a different problem (need to change the game end condition since game currently ends when a player gets back around to a "chain" they started). If the "drawability" of random word datasets is too poor, we may need our own curated dataset. This could be curated by players using the aforementioned random word autofill feature.
