Inputting notes when instrument editor is open causes focus shift to instrument editor.

Repro:

1. Open instrument editor.
2. Focus pattern editor, instrument column.
3. Enter edit mode.
4. Press a number.
   Result: Focus shifts to instrument editor.
   Expected: Instrument editor updates but focus stays in pattern editor.

upon editing the instrument column, the system calls an event function CFamiTrackerView::EditInstrumentColumn, which sets the current instrument to whatever the user inputs with CMainFrame::SelectInstrument.

in there, it updates the currently opened instrument editor with the current instrument through CInstrumentEditDlg::SetCurrentInstrument:

Dn-FamiTracker/Source/MainFrm.cpp

Lines 996 to 998 in 465125b

	// Update instrument editor
	if (m_wndInstEdit.IsOpened())
	m_wndInstEdit.SetCurrentInstrument(Index);

in there, it calls on the CInstrumentEditorSeq::SelectInstrument() to update the sequence panels; in that function, it sets the focus with SetFocus():

Dn-FamiTracker/Source/InstrumentEditDlg.cpp

Lines 220 to 224 in 465125b

	for (int i = 0; i < PANEL_COUNT; ++i) {
	if (m_pPanels[i] != NULL) {
	m_pPanels[i]->SelectInstrument(pInstrument);
	}
	}
