(svn r22312) -Codechange: Add GameOptionsWindow::BuildDropDownList() for construction of all dropdown lists in the GameOptionsWindow. -Change: Sort the items in the currency dropdown; separate the "Custom" item with a horizontal line from the rest. -Change: Separate default and NewGRF-supplied townnames with a horizontal line and only sort them within these groups. -Fix: Resize all dropdown lists in the GameOptionsWindow, so no text is truncated.
