Better nested include param analyze?

[HuNanZai]

when using fractal(0.13.0) in Laravel(5.1.45)

include=resourceA:fields(a|b|c).resourceB:fields(aa|bb|cc) won't work
so i have to write like this:
include=resourceA:fields(a|b|c),resourceA.resourceB:fields(aa|bb|cc)
it'll become a quite long query string when things getting just a little more complicated!

i wonder the reason why not support analyze the nested relations and params at the same time?
the include=resourceA:fields(a|b|c).resourceB:fields(aa|bb|cc) way.

the reason locates in the Manager.php's function parseIncludes, after explode(',', ....) the code start to load the param by : so the nested param is loaded and the nested info is abandoned.
so just adjust the order of the code here, after explode(',', ...) then explode('.', ...) and store the nested relation then load the param.
