Idea stolen from AB

* New rules
* Private header now links straight to the wiki page

* Gazelle bot auth code is missing
* Bot makes no attempt to connect to IRC

* Use jquery CDN for jquery
* Add meta hide-origin to not reveal users of SM to the CDN.

* Bad search and replace broke it

* Use smaller badges where appropriate
* Redice padding for cats_col
* Use larger caticon for the details pages
* Centre cat icon div within cats_col
* Keep the column as tight as possible by setting a low width

* Decent looking caticons that reflect all the categories
* Added in CSS and also added cats_col to artist.php
* Larger caticons in details.php

* Added base64 logo to global.css
* Removed URL reference to all style CSS

* Add post_id margin to allow non-badge posts to look OK
* Remove undeeded .badge_icon width as our nadges are bigger than OT

* Allow badges to be shown either full size 32x32 or a reduced 20x20
  size
* Reduce extra padding with badges and ensure the forum post heads do
  not look ugly even if user has no badges
* Remove donoer hearts from being shoen as we do not have donors yet and
  saves the time from having to find 32x32 badges for them

* Input input, selector and bbcode colour change to use dark blue
  instead of white, inline with the previous colour changes
* Forum posts now use same colhead_dark as other areas to it looks
  neater.
* Reimplented forum staff posts colour
* Fixed unread forum post colour to not use OT colour
* noty colours not used sugoi colours

* torrent-table grew to be ridulously wide on modern screen resolutions
  as it was set to 80% , set this to a more sensible 850px inline with
  what other stylesheets use.
* Menus were too wide, these are now narrower
* Artist page torrents table are now not too thin and instead of the
  width being robbed by the .sidebar , .thin is now extended for #artist

* All text in the site is now dark background light text, this will
  simplify the styling with no unreadable text issues to fix.
* Improved colours for tables

* Added imagetools::cover_thumb to handle the html and ::process
* Added to group and non-group locations in torrents/browse.php
* and artist.php
* CSS fixes
* Larger thumbnail popup on mouseover image as well as title, full
  image onclick

Also create seperate account security options page

This commit requires a new database table

Users can now add the orignal Japanese/Korean etc artist upon uploading
and also edit it in edit.php. Only torrent groups that have 1 artist
are currently supported as otherwise users would need to manipulate some
sort of 2d array in upload.php. Currently searching is not setup.

* artist.php shows orig artist if it is present in the same way
torrents.php does for torrent groups.
* Updated all forms, including a note on only supporting orig artist for
single artist torrents as well as hiding the field when >1 artist is
bring added.
* artist/edit and takedit.php support orig artist.

* This can be implemented later.

* Loop through $UsedCategories to generate filter links and .ghide() and
  .gshow() statements for each tr of the class that matches the category to
  to be filtered. Also allow for Show All.
* As nth-child is used for styling .ghide() and .gshow() natively breaks the
  zebra-striping. This is re-applied in apply_torrent_table_styling().
  The function removes CSS classes rowlight and rowdark with jquery :odd
  and :even CSS selectors Additional CSS were needed as nth-child cannot be
  referenced by .addClass().
* CSS styling for category filter links.
