Fixed "Shell" Names

The names for the suppressor shells need to be more unique. For example,
the Stepping action looks for energy deposits in the volume
"right_suppressor_log" to see if the right suppressor fired. The name
for the shell is "shell_for_right_suppressor_log",
"right_suppressor_log" is a subset of that, and it will trigger the find
volume name function. Energy deposits in the Al shell should not fire
the right suppressor.
Fixed binning

This is better binning, ranging from 0.5 keV to 5000.5 keV, instead of 0
to 5000 keV.
