Added Bootstrap Support and Bug Fix

[QuixThe2nd]

Changelog:

• Added Bootstrap support
• Fixed bug that would cancel out every character after a , (and possible other characters) in download's filenames.

There are hundreds more updates I've applied, spanning beyond the script itself, such as torrent signing and 7 different BEPs added in (such as http-seeds). Announce script was entirely rewritten with tons of community perks and updates (happy hour, download slots, much more).

I also produced a MySQLi version of announce.php which works well.

Additionally, the login system utilizes a custom account class providing token authentication, secure sessions and no more risk of "session fixation".

The use of array_key_exists() is also considerably slower than isset(), just something to note.
