Changed FunctionBase FilesystemContext base to working directory

* this changes filesystem context resolution for external function execution to be relative to the working directory
** this was changed to enable module support in BuildXSLT
*** ... which is in turn required as a foundation for extracting the detail transformations into a separate "StaticXSLT" application
* added parameter-less FilesystemContext constructor which defaults to the working directory
