Memory leak

[squidink7]

I've noticed a memory leak when running any GUI program. This can be replicated by running v run examples/showcase.v, opening a process monitor of your choice and watching the memory usage as you move the mouse around the window, hovering over different widgets. The starting memory usage was around 150MB, but after just moving the cursor around for a couple of minutes it got to 500MB+

There are leaks coming from v closures, don't know if it's the same here. However my application does not leak any more after fix. Lets see how it's fixed.
