Providing rounding to the wire endings as an option

[Sarthak Kalani]

At some point of time it would be good to provide an option of rounding the ends of wires as an option. When lines are interconnected they are already being done like that.

See for example visio vs yckt pdfs attached. (Check pdfs at same zoom levels).

Found a workaround to have rounded edges. Just retrace the path drawn by line :)

Explicit cap and join styles have now been added. You can change cap styles between square, round and flat and the available join styles include mitered (sharp), rounded (soft) and beveled vertices. Closing this for now.
