Standardize Windows builds

[wick-ed]

By now Windows builds do not include the same feature set as *nix builds.

UAC:

• Windows builds MUST have the same grade of automation as other builds
• Builds MUST include Windows services for bundled daemons
• All dependencies MUST be satisfied in an automated way e.g. building PECL extensions (or download it if it is built within the extensions build process)

The windows build was automated as such that the appserver extension gets built from source if it is not present already.
A build can now be completed using ant WIN-create-jar.
Therefor bullet points 1 and 3 are implemented.
Bullet point 2 "Builds MUST include Windows services for bundled daemons" is still open.
An evaluation of the current installer might be necessary to check if we are even able to achieve this.

The pthreads extensions also gets built automatically now.

New builds on Windows do feature daemons for appserver, watcher and bundled php-fpm
