7132539: Passing parameters to webstar app through DT does not work
was implemented in deployment toolkit for Mozilla branch only. Need to complete the implementation for IE.
Also implement recomendations from Alexey quoted below:

better avoid extra conversions and use local DISPID. Like:

    6] delete as pair to npstringToChar is wrong choice. Use delete[]

91 const char* str = npstringToChar(v);
92 if (str != NULL) {
93 jvmargs.push_front(str);
94 delete[] str;
