Addition of SF_FileSystem and SF_TextStream classes
Machinery tuning:
- freeze a predefined list of standard modules
in the python persistent storage
- error management reviewed to mimic Basic behaviour on wrong
arguments
Standard modules are predefined in scriptforge.py as well
Both lists must be synchronized on a hardcoded entry number
Basic has minor revisions:
- complex boolean expressions return -1 and 0 to Python
i.o. True and False => Add a CBool() function
- [User]TemplatesFolder properties of FileSystem omitted the final "/"
