Fixes of akimbo -> beta version.
First fix: if akimboautoswitch=1 and you activated grenade and taken akimbo, then there isn't automatic switching to akimbo immediately.
Automatic switching is after throwing manually grenade.

Second fix: if akimboautoswitch=0 and in the middle switching to pistol you taken akimbo, then akimbo appears in the hands, instead of single pistol.

Third fix:   if akimboautoswitch=0 and in the middle switching from pistol you taken akimbo, then you switch to chosen weapon, instead of akimbo.
