[patch] File Open dialog incorrectly accepts folder selection

[Don-vip]

The JOSM "File, Open" dialog accepts a folder as selected object(s) whereas only files are processed.
This prevents for example to paste a folder path in its file name text area in order to quickly display a folder's contents before selecting a specific file. Instead, the folder is selected by the JFileChooser and JOSM tries to read the folder contents.

Please find attached the patch.

The JOSM open file dialog accepts directories, as when a directory is selected it loads all images from it. This patch would destroy that feature.

It should probably also open all other files it finds in the folder, but this is a different issue.

I thought so also before, but whereas a lot of images is normal, e.g. loading a lot off GPX files surely kills josm, so I think current method is better :-)

Could it be at least an internal property ? I don't care about this images autoloading, I personally select them all when I want to load all of them... But I definitely want to paste a folder's path in the text input field in order to display its contents without having to reach it by clicking all the way through the explorer :( It's really a non conventional usage to allow folder selection when you want to open files, I find this behaviour very disturbing.

reopening so this is not forgotten :)

if the entered text in the address/location field is a directory, josm should first display it's contents.

ability to open all files in a directory should be provided by selecting that directory in the file listing, then specifically 'opening' it.

reasoning :

1. all other software does it that way :)
2. usecase : i have directory where i store gps traces and images. so occasionally i want to quickly get to that location to open one gps trace. i enter the path, hit 'enter'... and josm tries to open some 20gb of images.
