Moved creating index controller from generation to template

Solution shouldnt be much more than this

[feons]

@Bertuzb, I think this breaks existing apps that startup from index.

yes when they update it breaks, but this is a much better solution instead of appending unknown code during the compilation process.

Fixing it for any app will be really simple though, simply append Alloy.createController('index') as the last line on alloy.js and you're good to go
