- big renaming orgy (BRO): - changed filenames starting to "xotcl" into filename starting with "nsf" - adoped Makefile insfrastructure accordingly - removed compile flag XOTCL_METADATA and generic/xotclMetaData.c - changed compile flag PROFILE into NSF_PROFILE
- made error messages for failed conversions more consistent (note that tcl does not provide the parameter name in the error message, but user-defined converters do)
