Allow whitespace in else if

[Fabian Maurer]

The suggestion would be to allow more than one space between 'else' and 'if', als long as they are in the same line.
To avoid this problem:

label Start
    $test = 1;
    if($test == 1) then
        say "Creeper" "Hi.";
    else  if($test == 2) then // the 2 whitespace here prevent it from beein recognised as "else if", so the parser compains in the last line about a missing "end"
        say "Creeper" "Hello.";
    end
end //complains here

It'd be a good idea if composite keywords like "else if" would would be recognised by a regex. E. g. the regular expression "else\p{Blank}*if" would allow "elseif" and "else if" as well as else and if separated by as many whitespace characters as the user wants to use.

Implying MTS uses regex instead of a proper lexer.

MTS 2.0 will use Lua's elseif.
