Server side to allow three image modes: portrait, landscape and tall.
This code is currently active, but needs further testing. Code that was
responsible for only choosing one or two crop windows is disabled for
now, meaning all three crop windows are shown.
Correct crop size for portrait mode full screen.
Show some dimensions which can be used to obtain best results.
Changed the image upload modal a little. Increased width and added a
height dimension to allow overflow: scroll to work in the y direction.
This is so that very tall images don't prevent the user from seeing the
add slide button..
