GUI: Add "Paste" button in StorageWizardDialog

It pastes clipboard contents as code into 8 fields of that dialog.
(Clipboard support works with SDL2 only.)

"Open URL" and "Paste" buttons are placed in the left column under the
picture (because there is no room for 4 buttons in the bottom row).

Commit also adds "dropbox.bmp", which is just a square 115x115 picture.
Such pictures are would be used as Storages logos in that dialog.

In lowres there is no left column, so all 4 buttons are in the same row.
None of them are visible, because they are overflowed. Container has to
be added to continue working on them.
