Tardis:CosmeticBot

From time to time, a bot shall execute a script whose sole function is to clean up the code. It shall run on every page in the main namespace, as well as several other namespaces. This script will in no way change the way that a page appears. But it will perform a number of menial tasks on pages, such as:
 * the removal of extraneous spaces, per T:SPACING
 * the insertion of leading and trailing spaces in section headers, per T:HEAD
 * the placement of exactly one space following a full stop, which isn't required, but is allowed by T:SPACING
 * the placement of exactly one space between a symbol which creates a list (i.e., * and #) and the following text
 * consistent capitalisation of namespaces, such that — for instance — file: becomes File:
 * the elimination of some redundant pipe tricks — human would become simply human, for instance
