== filebrowser ==
fixes:
* Sequence editor not loading file typed in filebrowser file button (reported by Sergey on IRC)
* filename button doesn't match exactly typed in filename

notes:
* file specified in the filename button now gets added to 'files' list, even if not selected
* after matching filename (either by typing in exact match or using wildcards) the first match is assigned to the filename button.
