No unique range/dimension `..` token

[HippieKiller]

Hi BeRo,
I noticed when looking through the code that the range .. symbol used in defining Array dimension doesn't have it's own token, and instead shares the TokColon token, which means you can compile weird stuff like this:

var x: packed array [1:5] of char;

instead of array [1..5], and also you can use the .. instead of : for defining types too

var y..char;
