Wrap option

[mdedetrich]

This pull request adds the wrap option (default is true). If wrap is set to false, angular-carousel won't loop back to the start if it hits the last index (and vice versa)

Hey, thanks for the contribution !
Isn't wrap the same as allow-loop ?

[mdedetrich]

I just had a look at the code, I think wrap works a bit differently (for example, it will stop the looping even on things like auto slide). Allow loop only appears to work in regards to controls

I think that wrap will work the same way that auto loop does if you do happen to have controls
