Enable Synthetic Spreads for the Kobo Forma.

Browse Source 
Rotating the device into landscape mode will cause it to display two
pages side by side. This is particularly useful for input comics whose
spreads are already split into two files.

See https://github.com/kobolabs/epub-spec#synthetic-spreads for
additional information on synthetic spreads.

(Tiny drive-by: Add Kobo format to list of profiles for which the AUTO
format is EPUB)
