[ticket/9801] Allow display of page outside board directory on viewonline

Until now, the preg_match didn't take into account that a page might be
outside the board directory. After this change, the regular expression will
allow preceding dots and slashes. Paths like ../../test.php will be allowed.
The page will be unknown in viewonline.php and it will revert to index.php as
current page. However, the core.viewonline_overwrite_location event will
receive proper info of the page the user is on right now allowing a listener
to change the info that is being displayed.

[ticket/11148] Add mimetype guesser to filespec and fileupload class

The mimetype guesser will be used to get the mimetype of uploaded files.
Until now, this was only used for files uploaded with plupload. If a file
doesn't have a mimetype supplied, we will now try to get the correct mimetype.

[ticket/11148] Remove unneeded variable mimetype and use type octet-stream

The variable $mimetype is not used in the method local_upload() afterwards
so it shouldn't be assigned. The correct default mimetype should be
application/octet-stream and not application/octetstream according to RFC 2046.
