Change "Save As…" to "Save To…" when multiple photos are selected in the camera roll
The camera roll (scrolling array of photos/videos at the bottom of the Cheese interface) is a multiselect object: more than one image/video can be selected at once.
When right clicking on the camera roll, there is a "Save As…" option, which brings up a new filename selection dialog. This makes sense when right-clicking a single object is selected.
When multiple objects are selected, though, "Save As…" should change to "Save To…" option, and it should bring up a directory selection dialog, so that all of the selected images can be exported to the selected directory.
