Fix module loading logic

Modules are located on the `modules` folder on the project.
By default, kickstart will put itself on the `compile/modules/kickstart`
before any folder is linked there as well. This give the possibility of
overriding which kickstart project will be deployed with you.

Kickstart is treated as an special folder, given that the projects
requires its functions. So, it is loaded before all of the modules, and
skiped looping over the `modules` folder.
