Gamepads - small improvements

[fanick1]

• enable reattaching gamepads during player's controls assignment
• [Linux] fix timing issue/exception thrown when processing the JOYDEVICEADDED event after the device has been detached already (some gamepads simply detach from the system when attached and reattach as completely different device just a fraction of second later)

Asi jo, uz jsem nemel sily :). Jeste to porefaktoruju. Zavedl bych nejakou tridu "Event processor", ktera by se starala prave o tohleto. Jeste me napadlo, ze by tenhle polling pri prirazovani controllu slo nahradit nejakou "prirazovaci" GUI komponentou, ktera by proste mela focus a ty on keydown eventy by se ji zpropagovaly ( z Application nebo teda z toho Event processoru). To by ale znamenalo naimplementovat focus. F

In source/Menu.cpp https://github.com/odanek/duel6r/pull/84#discussion_r216592521:

     SDL_Event event;

• while (SDL_PollEvent(&event)) {
• // Eat all remaining keyboard events;
• int result = 0;
• //TODO This logic duplicates event processing logic in Application. Should be refactored.

Nejde to teda odsud i z Application hodit do nejake funkce, ktera by se volala z obou mist?
