SS: Fixed startup hangs in "Device Reign", "Real Sound", "Resident Evil", "SD Gundam G Century S", "Super Tempo", "Tennis Arena", "Tilk", "Yuukyuu Gensoukyoku", "Yuukyuu Gensoukyoku 2nd Album", "Yuukyuu Gensoukyoku ensemble", "Yuukyuu Gensoukyoku ensemble 2", "Yuukyuu no Kobako Official Collection", and "Zero4 Champ".

Reworked how input grabbing is handled. The new way uses only one key combo(CTRL+SHIFT+Menu), and will adapt its behavior based on any keyboards being selected on any virtual input ports or not(refer to the documentation for full details). A new setting is added, "command.toggle_grab", and two settings were removed, "command.toggle_grab_input" and "command.toggle_cidisable".
Emulated keyboard(FKB, Tsushin, Saturn) key state is now only updated when input grabbing is toggled on.
