[Exult-general] avatar movement in combat slightly flawed

[Ryan N. <tri...@me...>]

Just noticed there is a minor problem with the way the avatar move in 
combat (due to mouse input). Basically, the avatar will only move IF the 
mouse is being moved. If you hold your finger on the right button, without 
moving the mouse, the avatar will move a few steps, then stop.

I've tracked this down to the combat schedule using Actor::start() which 
ends up setting int Actor::frame_time, which is then used to detect if the 
actor (the avatar in this case) is moving when calling Actor::is_moving(). 
The code in Handle_events to automatically restart the avatar's movement 
once he has stopped after the few steps uses Actor::is_moving().

I'm unsure how to fix this problem.
