Simplify the API

[tristanlins]

I will continue this project soon, but I want to simplify and rework the whole system:

The main aspect is, that the "integration" part will be dropped. It make no sense to enforce a specific integration layer, in a filesystem abstraction layer. This must be part of the integrating system (e.g. a symfony bundle).

Due to drop the filesystem configuration, the incomplete "live reconfiguration ability" make no sense anymore. The integrating system may provide this feature. The same applies to the requested registry feature (see #72).

I also want to remove the Filesystem class. It is too complex and make no sense, if we can work directly with the adapters. So all adapters will be rename back from "_Adapters" into "_Filesystem".

We may provide a "default integration and configuration" package in the future, but this must be a separate project.

Totally agreed!

Okay, I have finished my work so far. Here is a short summary what I have done in the last 49 commits from the last 0.9.1 and the new 1.0-alpha1 release.

A have not removed the Filesystem class. While overwork the API, I find out that splitting the adapters from the filesystem is a good idea to split the public from the internal API. Most of the API still exists as in the previous version.

What I have removed:

• The cache classes (that are never used yet)
• The global configuration object (each adapter must store its own configuration).
• The symlink, mime and hash functions from the File class (these are now plugins)
• The AggregateAdapter class (it is replaced by the MountAdapter class)
• Some dead code

I added:

• Filesystem plugin support (symlinks, mime and hash functions are now provided through plugins).
• Added event support.
• Added stream support directly into the Filesystem class.

I improved and cleaned the public and private API and moved some convenience methods into the Util or the new Validator class. After all, the new build is working again :-) https://travis-ci.org/filicious/core/builds/32444809

At least, I have reworked the project page, it is now a github page, see https://github.com/filicious/filicious.github.io Be patient, you will not see the website yet, I transfered the domain to another registrar and the transfer is not finished yet. It should be available in one or two days.
