luainstance: remove utf8 parameter from RenderString, add center

Browse Source 
Everybody should always be using utf8 anyway, so remove the "utf8"
parameter from RenderString and replace it with a "center" parameter
which centers the string horizontally in its box.

new usage:
   RenderString(font, text, x, y, color, boxwidth, boxheight, center)
defaults:
   color = COL_MENUCONTENT, boxwidth = window's width minus x
   boxheight = 0, center = 0
