Charset bugfix

[Nadav]

In the blue skin, the charset isn't being set by the lang.php
The problem?
skin/blue/header.html
find:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
and the solution?
Replace to:
<META http-equiv=content-type content="text/html; charset={L_Charset}" />
I hope I helped someone ;)
