Tighten LSF integration by adding support for affinity settings

 Provide tighter LSF integration by correctly handling scenarios where the user has asked LSF to assign bindings. Fix a couple of typos in lex parser definitions. Tell hostfile parser to ignore binding designations in hostfiles. Add a control flag to indicate that cpusets were provided as physical cpu ids.
