API sites: Support <default> inside options, fix hiding of gutter

Due to some bad logic, the gutter was always displayed by default, the
reverse of what the code intended. Changing the actual default now to
keep the previous behaviour, but allowing opt-out, which the new
<default> element is now using.

Fixes #64
