Pick Page Editor fonts and images from the platform's banks

The font and image rows are now dropdowns filled from <sedona home>/ontrol:
fontBank/imageBank on Rion, fontBankXL/imageBankXL on Orion. Orion lists
.oxfl fonts in landscape and .oxfp fonts in portrait, read from the
platform service's screenOrientation (loaded from the device in live mode
when the tree has not reached it). Images show their file extension while
the slot keeps the bare name. The font dialog is gone.

In portrait the Page Editor draws a 480x800 screen in
frame_orion_portrait.png, and the canvas renders text with the .oxfp
fonts, whose glyphs are stored a quarter turn anticlockwise.
