Add first and last @ vars to each helper

Currently first condition can be done with something like {{#unless @index}} but detecting last state is not possible.

Implementing {{#last}}...{{/last}} and {{#first}}...{{/first}} but including {{^last}}...{{/last}} and {{^first}}...{{/first}} and supporting {{else}} would be hella cool. {{!! Thanks !!}}

I was also looking how to do this and as it turns out it's not that comlicated. Find line 138 in file handlebars.js and change to

if (data) {
    data.index = i;
    /* NEW */
    data.index1 = i + 1;
    data.first  = (i == 0) ? true : false;
    data.last   = (i == (context.length-1)) ? true : false;
}

Now you will have access to @index1, @first and @last variable inside #each.

{{#each data}}
    {{@index1}} 
   {{#if @last }}
       Last entry!
    {{/if}}
{{/each}}

@gecbla Yeah I think thats just about what the implementation would look like. Pull requests accepted :)
