Folder creation capability

[kirillt]

User should be able to create new folder without escaping an app into file browser.

But only in saving mode.

@kirillt What do you mean by saving mode here please?

[kirillt]

@tuancoltech this depends on context, but the filepicker should allow an app to specify mode of operation. So, "open" mode must allow user to choose some existing file. And "save" mode must allow choose an existing location, or create a new location, i.e. folder or sequence of folders.

In other words:

• "open" mode locates a file
• "open" mode doesn't allow creating folders
• "save" mode locates a folder
• "save" mode allows creating new folders
