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.

This way Ican see a diff of my changes to create sugoi CSS

This was an automatic mass-replace. Manual replacement of array(...)
will continue

- Removed unused JS functions
- Inlined functions not often used
- Minimized some overly verbose functions

Fixes #27

This allows for some browsers like chrome mobile to change the color of
the address bar to smoothly match the theme of the page

Also file permission cleanup

This consists mostly of commits I somehow skipped over and didn't patch
into the public repo
