Escape filenames in wxFileDataObject::GetDataSize/GetDataHere
On wxGTK, wxFileDataObject::SetData calls g_filename_from_uri which percent-decodes URIs. No corresponding percent-encoding was done in wxFileDataObject::GetDataSize/GetDataHere. Use g_filename_to_uri instead in so that filenames are properly escaped. This commit also fixes the data being truncated if it contains non-ASCII characters on wide-character builds, see the memcpy arguments in the original code.
