fixed split

[taiyu-len]

when focus is on workspace, and there is more then 1 child, splitting will now split properly.
it now acts as if the container is created around workspace, without actually doing so.

┏━┯━┓
┃ │ ┃
┗━┷━┛
with vertical split (+ new view) becomes. before it just changes workspace layout.
┏━┯━┓
┠─┴─┨
┗━━━┛

although the effects of this cant be seen yet as focusing still needs to be fixed. (i did test it with a buggy focus fix, but im not pushing that)

what we are currently using to set the focus focus_view doesnt support focus in the middle of the layout tree, so when workspace has children, focus cant be on workspace.

oh and i also moved the if(parent->focused==child)parent->focused=NULL); into the free_swayc function.
