Several fixes
Merge pull request #75 from dorkster/fixes

Remove empty soundfx and add developer console
remove empty fields
Fix dialog. For boss enemies use only one category
Fix bombs by making bomb tick a passive power

The bomb tick wasn't being triggered because the bomb would never "enter
combat". So instead, we use a passive power that triggers regardless of
the bomb's combat state.
