[PR modula2/119650, PR modula2/117203]: WriteString and Delete are missing from base libraries

This patch introduces a Write procedure for an array of char,
the string and char datatype.  It uses the m2r10 style of
naming the module on the datatype.  This uncovered a bug
in the import handling inside Quadident.  It also includes
an Unlink procedure from a new module FileSysOp and a String
interface to this module.
