Improved modules and name resolution

A project log for Argentum programming language

It automatically prevents all memory leaks. It doesn't use GC, so no pauses. It's compiled to machine code. It's crazy safe and fast.

Today Argentum got small but fundamental improvements:

How it was previously (file ``):

using sdl;
using utils;
using gui;

class Scene{
    sdl = sdl_Sdl;
    w = sdl_Window;
    rnd = utils_Random;
    flare = sdl_Texture;
    star = sdl_Texture;
    background = sdl_Texture;
    foreground = sdl_Texture;

How it is now:

using sdl { Window, Sdl, Texture }
using gui { Actor, Group }

class Scene{

    sdl = Sdl;
    w = Window;
    rnd = Random;
    flare = Texture;
    star = Texture;
    background = Texture;
    foreground = Texture;

Previously any compound names like `sdl_image_mySurface` were able to be created and used in any package. And they always had to be written in full.

Since now names should follow rule: `packageName_functionOrClassName` (for example: `sdlImage_mySurface` or from example above `demo_Scene`. And since names are bound to a module, no need to write them in that long form.

All names defined in a module `demo` are automatically `demo_*`.

When a module declares some dependency with the `using` directive, it may list all names to import and use in short form: `using gui { Actor; Group; }`

If names from different imports collide, give them aliases: `using gui { Control=Actor; }`
Now `Control` can be used instead of `gui_Actor`.

TL;DR: Argentum names just got better.
