grapherdisplay option added

[Tontonitch]

thanks for the plugin.
I added the option grapherdisplay to overwrite the hostdiplay argument in grapher url for pnp4nagios (atm only).
Problem is that if you use hostdisplay argument with $hostname$ and you use two services with different options for one host the webpage will overwritte everytime - so you have to use hostdiplay with for example $hostname$- $servicedesc$, but then you grapher url is wrong.
