commit 562332df73781c1e56ce9123542334cc1d91b143
Author: Lukas Bulwahn <lukas.bulwahn@oss.bmw-carit.de>

explicitly cast to std::vector<double> to make gcc6 happy
With gcc6, compiling image_publisher fails with this error:
```
/[...]/image_publisher/src/nodelet/image_publisher_nodelet.cpp: In member function 'virtual void image_publisher::ImagePublisherNodelet::onInit()':
/[...]/image_publisher/src/nodelet/image_publisher_nodelet.cpp:180:43: error: ambiguous overload for 'operator=' (operand types are 'sensor_msgs::CameraInfo_<std::allocator<void> >::_D_type {aka std::vector<double>}' and 'boost::assign_detail::generic_list<int>')
camera_info_.D = list_of(0)(0)(0)(0)(0);
```
After adding an initial explicit type cast for the assignment,
compiling fails further with:
```
| /[...]/image_publisher/src/nodelet/image_publisher_nodelet.cpp: In member function 'virtual void image_publisher::ImagePublisherNodelet::onInit()':
| /[...]/image_publisher/src/nodelet/image_publisher_nodelet.cpp:180:65: error: call of overloaded 'vector(boost::assign_detail::generic_list<int>&)' is ambiguous
| camera_info_.D = std::vector<double> (list_of(0)(0)(0)(0)(0));
```
Various sources on the internet [1, 2, 3] point to use the
`convert_to_container` method; hence, this commit follows those
suggestions and with that image_publisher compiles with gcc6.
