Appending and Linking
* Linking Operator, invokes filebrowser for Append/Link
* Separated the append/link function into three parts:
** BLO_library_append_begin finds main for appending
** BLO_library_append_named_part appends one Object,Group, Material, ...
** BLO_library_append_end actually reads and expands the libraries
NOTE 1:
I also changed the returned properties for the filebrowser operators to the following convention:
"path" - the full path to a file or directory, means what is in directory + filename buttons in filebrowser
"directory" - the content of the directory button in filebrowser
"filename" - the content of the filename button in filebrowser
Usually only path should be required, but in some cases it might be more convenient to retrieve the parts separately.
Ton, Brecht: If you have time to take a look, let me know if anything needs to be fixed.
