Issue #1535: select appropriate file filter corresponding to "Mode"

This reorders the filters in the import file dialog of the Edit Cell dock
so the first entry is always in accordance to the currently selected mode.

This will also facilitate the translation of the filters, because the
translations can be reused and written without special syntax characters
(";;").

"%1 Image" is also used instead of a concatenation, because the word
order in translations will vary.
