* Swap conditionals around on adlists file handling
* Add comments to both gravity_Collapse() `awk`s
* Removed unnecessary "${str}" from gravity_Pull()
* Merge function variables into local line
* Place .phgbp suffice on mktemp, so patternbuffers can be cleaned up all at once in gravity_Cleanup()
* Removed success="false" from $httpCode case, placed empty success var in local
* Reordered $httpCode case numerically because I can
