Issue #53: add --scriptPath flag to the following `browse` and `find` commands:
  browse [--scriptPath=<tode-path>] psender [#]<selector>
  browse [--scriptPath=<tode-path>] references <variableOrGlobalNameOrPathRef> [@filter-block-path]
  browse [--scriptPath=<tode-path>] rsender <regex-pattern> [@filter-block-path]
  browse [--scriptPath=<tode-path>] sender [#]<selector> [@filter-block-path]
  browse [--scriptPath=<tode-path>] source <regex-pattern> [@filter-block-path]
  find [--scriptPath=<tode-path>] psender [#]<selector>
  find [--scriptPath=<tode-path>] references <variableOrGlobalNameOrPathRef>
  find [--scriptPath=<tode-path>] rsender <regex-pattern>
  find [--scriptPath=<tode-path>] sender [#]<selector>
  find [--scriptPath=<tode-path>] source <regex-pattern>

For the `browse` command, the definition leafNode list will recalculate on refresh...
