Update to Blade for L5.3

[vpratfr]

There were a few major additions to loops in L5.3, any chance to get them in your package? Thanks a lot!

use $ composer update for your project. Blade Packages will be updated to version 5.3. Then, you can use the features of 5.3.

I did test for loop variable methods , no problem.. I'll try as soon as possible in other methods.
