Add Insert feature for external Kode editors

Insert Kode for external kode editors just like how pressing formulas on the formula list inserts it to the current cursor position

something like this:

String kode = "My edited Kode";
i.putExtra("org.kustom.KODE", kode);
// Weather to insert kode in the current cursor position
i.putExtra("org.kustom.extra.INSERT", v.getId() ==;
setResult(RESULT_OK, i);
