Update v2.12

• Fixed XSS injection in donation list and player search, thanks to Xniveres.
• Rewrote the checks at Vote4Coins. It is completely solved.
• Remove extra files and unused functions. Fixed performance issues in existing functions.
• Fixed a serious issue on the admin side: in old versions, language/module/theme links were in the form, so they could be changed by someone with admin rights to upload any zip file to the site.
• Introduced default values for the columns that are created in the account during the first installation.
• Removed the query that excluded banned players. The method was a very bad poor, and on a server with a lot of players it would use a lot of mysql.
• Rewrote the function that checks for updates in administration. Now it is checked only once a day, so the official Metin2CMS website is no longer accessed.
• Fixed captcha, the problem was occurring when the site was not on the main domain.
• Now the character deletion code is a number.
• Updated PHPMailer and PCLZip libraries.
• Added a new language: Arabic.
