Introducing PageCompiler and ApacheConnector

As promised a few days ago, here are two new and cool addition to POCO.

PageCompiler is a simple compiler that translates HTML pages containing embedded C++ code (using syntax familiar from JSP and PHP) into HTTPRequestHandler classes.

ApacheConnector is a module for Apache 2.x that allows you to use POCO HTTPRequestHandler subclasses in Apache. The simplest way to write Apache modules.

The sources are in the Subversion trunk and will make it into coming POCO releases.
Documentation (in PocoDoc format, but human-readable) is in the doc directory of each project.

Feedback and contributions wanted!
