add swipejs as submodule
swipe: initial try
force italic definition
do not add unnecessary js code
improve swipe gallery
missing files
add a background that occupies the whole window, because we sometimes have some visual glitches do probably to pixels parts
prevent page scroll to top when closing the gallery with the button
disable keyboard-based navigation for embedded maps
ensure that images won't be too much scaled up, which would make them look very blurry

note: max-dimensions might need some tuning
disable zoom when gallery is active
swipe gallery: use MI or BI images depending on screen size
swipe:
 - i18n
 - MI images for small screens, BI for big ones
not sure that we wan't to use async load here, because of dependencies
enable swipe gallery only for moderators (temproray, for tests)
Merge branch 'swipe'
