Title: Use const char* instead of char* for strings in messages.

The present implementation has GCC complaining thusly:

~~~
warning: deprecated conversion from string constant to 'char*' [-Wwrite-strings]
feedback_msg_.header.frame_id = "base_link";
~~~

Seems to compile and do the right thing for me.
