Add package include dirs config

Fix getRealPath returning corrupt path.
This allows you to specifying a list of include dirs under [package], like:

[package]
name = "blabla"
include_dirs = ["include"]

There are many libraries that include paths to header files like this,
so when including a header file, you dont have to specify relative path
to header files (which can be long), and you can use same path
no matter where you are including header from.

Currently include_dirs is not propagated to dependant packages
and im not sure if they should be, from the looks of it the reason
you want include_dirs is internal package setup.
