labels overlapped with others #73

Hi:

I found that the labels may overlap with each other once there are a log of features in the certain area, screenshot:http://pbrd.co/RaUk5E.

So I wonder how does vtm handle the overlap problem? Is it necessary to simplify the data in the server side?

The improvement of label and symbol placement is a big fat TODO item on my heap. The current implementation is very limited. There is not overlap checking for the symbols currently but it could be added to the /* add symbol items */ section in LabelPlacement
