Support `Fish and Chips` section
Section names are also used as the title of the list pages, but naming section folders as `Fish and Chips` and similar didn't work very well.
This commit fixes that.
This commit also changes the title casing of the section titles. Some may argue that this is a breaking change, but the old behaviour was also pretty broken,
even for languages that use title capitalizations, as it didn't follow any particular style guide, `fish and chips` became `Fish And Chips` etc.
Now it just turns the first letter into upper case, so `Fish and Chips` will be left as `Fish and Chips`.
People wanting the good old behaviour can use the `title` template func.
