Schedule: sort rooms with S-number first

[hugovk]

Wednesday looks like:

But when you go to Thursday or Friday, suddenly "Glass Room" appears and moves the keynotes to the right:

Instead, sort rooms without an S-number ("Glass room", "Fishbowl") last:

This also means Monday/Tuesday change from summits then tutorials:

To tutorials then summits:

But I think that's fine.

Thanks for the patch!

We were discussing the problem with Marcin a few days ago, and in general I think it's better if we go with a predefined order of rooms – either coming directly from pretalx, or from programmeapi, or hardcoded in the the website. Some of the new things on the talk pages will require a predefined room order.

A stable sorting algorithm would be also be good enough, but explicit order might be simpler and easier to understand and maintain.

I think it'd be better to do the predefined order here in the website.

Yep, we want do it on the website.

I can update this PR.

Here's the list of rooms:

• 2.017/2.018
• Exhibit Hall
• Fishbowl
• Glass room
• S1
• S2
• S3A
• S3B
• S4
• S4A
• S4B

What order would you like?

What order would you like?

I think this

Tutorial days:

• S3A
• S3B
• S4A
• S4B
• 2.017/2.018
• Fishbowl

Conf days:

• S1
• S2
• S3A
• S3B
• S4
• Glass room
• Exhibit Hall (for posters) floats on lunch break so not sure if the order matters for the purpose of the schedule display.

Updated, looks like:

If rooms are not listed in the order, or if we do not give a pre-defined order, what would the behaviour be? To me, what makes sense in terms of sorting priorities:

• pre-defined order
• pretalx order
• alphabetical order

The current new order in preview help me breathe better, so thank you!

This PR sorts by the predefined order, and for rooms not listed there, they're put in alphabetical order at the end.
