Fixed many build warnings

[WiiDynamit]

If you want to pull this Changes it would fixe some building warnings that is just annoying warnings that I have fixed just for fun.

I even have a own made Hello World that I write from scratch (the library's is copy as needed from this Hello World) but it compiles but not creating the elf file so I need to find out what is the cause and I will release more "advanced" Hello World but still hopefully less recurrence of some stuff in the main code it self ;)

Back in late 2016, devkitPPC revisions 28 and 29 were released. Version 28 has changed how an "int" was defined, and version 29 kept this change.

I have no clue why they did this, as it pretty much breaks everything that uses ints (such as this project).

So what you've done is basically add support for devkitPPC r28/r29, instead of r27, which in my opinion isn't a bad thing.

Perhaps this should be merged into a separate branch, so that we also have the r27 version of the code readily available.
