Modified parse_token() to allow for '-' characters in molecule names (derived from file names, etc.)

Instead of throwing a RelaxError if an invalid range is found, it is assumed that the '-' character
does not signify a range and is treated as a string character which is part of the token.

Deletion of the test_parse_token_range_failx() unit test.

parse_token() no longer raises RelaxErrors with invalid range tokens (as they are assumed to be
standard string characters instead).
