Corrected the verilog parser's behavior with respect to string

definitions:  Now correctly parses everything from the definition
name to the end of line as the definition value.  Also:  The
search for definitions in the body of the text does not reject
non-alphanumerics "_" and "$" in the definition name, without
which definition names containing those characters will go
unrecongized.  Have not yet extended this to multi-line definition
values.
