Drag-n-drop open folder

[patspam]

Dragging a file onto Padre opens it in a new tab. In a similar vein, it'd be nice if dragging a folder onto Padre triggered an Ok/Cancel? dialog that said something like:

"Folder X contains Y files, do you want to open them all in Padre?"

And then if you choose to proceed it opens all the files.

Currently, dragging a folder into Padre causes a blank tab with the name of the folder to be opened.
