Allow catch to specify what is caught
*: Default to the same as Tcl. Not signal, eval, exit.
*: Use 'catch -exit' to also catch exit.
*: Also map for standard return codes: [info returncodes]
*: Also Jim_ReturnCode()
*: Add Jim_FindByName() for searching in a char* array
*: Fix 'info nameofexectutable' if $::jim_argv0 is not set
