Implemented basic page compilation facilities

* templates in 'template/compiler' are automatically generated
** required datasources are extracted and merged automatically
** 'pages.xsl' is currently a dummy compiler
* moved context helper templates into context stylesheet
* added compiler directory to meta DOM
* modified generator and transformer helper templates to enable usage of DOM as input
