hgrc.5.txt: mention hgrc categories with higher precedence first

Reordering the FILES section accordingly.

The previous ordering of categories might have been nice from the
viewpoint of a site admin doing an initial install, but presenting a
higher-precedence-first ordering is more relevant and natural for the
average end user, since he will most likely resort to editing rc files
in the order of their precedence, overriding whatever "sane" defaults
are coming from more general files.

Note that this patch does not change the texts, it just moves them.
So, whatever bugs, grammar errors, or typos may have been in the texts
before this patch: they are still there. On purpose. Because this patch
here does not want to reword texts while moving them.
