fix: Prevent crashes caused by client_entergame and other minor bugs.

[kokekanon]

1.- fix: crash game_entergame if httpLoginBox is boolean

produced in #647

I think httpLogin is always boolean, but I haven't studied pr 647 enough.

    if type(httpLogin) == "boolean" then
        enterGame:getChildById('httpLoginBox'):setChecked(httpLogin)
    else
        enterGame:getChildById('httpLoginBox'):setChecked(#httpLogin > 0)
    end

Error:

ERROR: Lua exception: /client_entergame/entergame.lua:270: attempt to get length of local 'httpLogin' (a boolean value)
