patch [#23968] filter_filetypes property to allow operators to filter by file extensions in the file selector

modified the patch to store the string internally rather then an array of allocated string pointers, less hassle with memory allocation.
changed to use fnmatch, so *.foo is needed (not .foo as with the patch)
