WIP cleanup
* Changed supernova/eventHorizon variables to match their purpose * Add gravity_DNSLookup() function * Ensure all comments are clear and relevant * Use && instead of || in gravity_Collapse() * Renamed existing functions, and placed them in order of script execution * Use \t instead of literal tab in gravity_ParseFileIntoDomains() * Replace instances of "truncate" with : > (e.g: gravity_Schwarzschild()) * Ensure correct variables are local'd * Use phrase "Cleaning up stray matter" when gravity_Cleanup() is called * Add black/white/wildcard switches for list.sh * Ensure necessary functions are called when modifying black/white/wildcards Signed-off-by: WaLLy3K <wally3k@pi-hole.net>
