Use a File class to wrap file compilation logic

[antoniogamiz]

Steps to take:

• Add a simple File class only containing four basic attributes. Something like:

class File {

   has Status  $.status;
   has Str     $.path;
   has Instant $.added;
   has Str     $.cache-key;

}

• Integrate it in the system.
• Add methods to compile the file, etc.

Why?

[antoniogamiz]

It's a item in the TODO list...

... which I added, but I'm not really sure why now...

To ease adding/deleting files from the cache I think. And to fix the problem with reallocation of pod files.

Ah, right :-)
