Lua Fix utf8encode, remove utf16 functions

Browse source 
The auto generated utf8/16 encode/decode functions did not work.
Upon implementing them correctly I found that lua handles the utf-8
form properly but I could not get utf-16 to work without crashing
maybe someone can come along later and implement utf-16 safe string
functions but for now utf-16 is removed.
