Additional mime types for file identification and a few fixes.

Some of the existing mime types received extended matchers
to fix problems with UTF-16 BOMs.

New file mime types:
 - .ini files
 - MS Registry policy files
 - MS Registry files
 - MS Registry format files (e.g. DESKTOP.DAT)
 - MS Outlook PST files
 - Apple AFPInfo files

Mime type fixes:
 - MP3 files with ID3 tags.
 - JSON and XML matchers were extended
