New file mechanism

[EmmanuelMess]

Proposal for new implementation of new internal file mechanism

Rationale

This would make adding new file types more modular, and have a simple interface. This is a replacement for HybridFile.

Implementation

Similar to File.java as implemented by the standard library.

1. An AmazeFile class that provide all basic interactions for files, it contains a reference to a singleton deriving from AmazeFileSystem that provides all basic operations on files specific to Amaze. AmazeFile is uniquely determined based on a path. It has no cached information and it is parcelable.
2. The AmazeFileSystem is an abstract class that provides all most basic operations for files. There is one subclass per AmazeFile.
