Modular-Kicad milestone B), major portions:

*) Rework the set language support, simplify it by using KIWAY. Now any major frame with a "change language" menu can change the language for all KIWAY_PLAYERs in the whole KIWAY. Multiple KIWAYs are not supported yet. *) Simplify "modal wxFrame" support, and add that support exclusively to KIWAY_PLAYER where it is inherited by all derivatives. The function KIWAY_PLAYER::ShowModal() is in the vtable and so is cross module capable. *) Remove the requirements and assumptions that the wxFrame hierarchy always had PCB_EDIT_FRAME and SCH_EDIT_FRAME as immediate parents of their viewers and editors. This is no longer the case, nor required. *) Use KIWAY::Player() everywhere to make KIWAY_PLAYERs, this registers the KIWAY_PLAYER within the KIWAY and makes it very easy to find an open frame quickly. It also gives control to the KIWAY as to frame hierarchical relationships. *) Change single_top to use the KIWAY for loading a KIFACE and instantiating the single KIWAY_PLAYER, see bullet immediately above. *) Add KIWAY::OnKiwayEnd() and call it from PGM_BASE at program termination, this gives the KIFACEs a chance to save their final configuration dope to disk. *) Add dedicated FRAME_T's for the modal frames, so m_Ident can be tested and these modal frames are distinctly different than their non-modal equivalents. KIWAY_PLAYER::IsModal() is !not! a valid test during the wxFrame's constructor, so this is another important reason for having a dedicated FRAME_T for each modal wxFrame. On balance, more lines were deleted than were added to achieve all this.
