First alpha release!

The first 1.0 alpha release is ready after a great rework.

My main focus on this release was issue #78.

Here is a short summary what I have done in the last 49 commits from the 0.9.1 to the new 1.0-alpha1 release.

First I have not removed the Filesystem class, as I planned. 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 before.

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 have 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 :-)
