Implemented a method where LANG_* strings can be referenced

Browse source 
by constant id's - reducing code overhead associated with
looking up the global strings variables.  Kind of.  Just compare
the assembly output...

// Changed by Amir Szekely 3rd August 2002
// Now supports more than one language in each installer
// Please note that all of these define the offset not the string itself.
// To get the string it self use process_string_fromtab, GetStringFromStringTab or STR().
// Modified by Dave Laundon 10th August 2002
// In many places, these strings are now referenced by an ID (just their offsets
// into the (common|installer|uninstall)_strings structures) through *_from_lang
// and *FromLang functions - removing code-costly references to the
// cur_(common|install|uninstall)_strings_table globals. Common strings are
// identified by IDs >=0 and install/uninstall strings by IDs <0. What's more,
// these IDs fall between -128 to +127 and compile to tiny 2-byte PUSH <8-bit>
// instructions when being passed to the functions.
#define STR(x) GetStringFromStringTab(x)
typedef void *langid_t; // Just so compiler can warn if an ID is given to a
// function expecting a string offset and vice-versa.
