Title: charts function and options clean up

Per our mailing list thread:
http://groups.google.com/group/incanter/msg/2f7fa15e642db72c

These commits do as I proposed and allows for the `xy-plot*` function to be used publicly. The formalizing of the `:title` option also fixed some latent bugs in the other chart macros.
