Remove burster and cbrtester

Burster and cbrtester, while useful at the time for debugging specific
issues with the routers, are somewhat redundant with the functionality
of the bwtester applications.
Moving forward, the idea to integrate the useful bits of these two tools
into the bwtester instead; see #210.
