feature 2407 added: display upload limitations before file selection (file

maximum size, maximum dimensions, allowed file types). The maximum dimensions
are calculated for GD only (because Imagick and External ImageMagick are not
using PHP memory as far as I could find on the web).

bug 2408 fixed: change term "old style form" into "browser uploader" and
"multiple file form" into "Flash Uploader" (based on WordPress user interface)
