Replaced function-like data resolution with template applications

* e.g. article and tag support data is now fetched through direct _XPath_ template applications
** this required the introduction of a special `resolve` mode to prevent interaction between support and main content resolution
** in most cases arguments had to be wrapped inside helper constants to enable selection of e.g. article support data via the `@handle` attribute using the current elements `@handle` attribute
* analogously to the recent changes in _StaticXSLT_ this commit aims to improve the XSLT code style used in generating this static website
