Setup Preset Messages for Posts

If you are wanting to have the ability to setup a default message for a post when someone clicks the "message" button, this is possible with 1.4 and up.

Use Cases:
1. For property posts, being able to let the receiving party know which property you are interested in by bringing in the property title/address and even some of your information that they can contact you at.
2. Classifieds, you can setup preset buttons for phrases such as "I am interested" or "I have a question about" or even just "Hello"

For example to message current post with Hello as preset

@site(url)/inbox/?chat=p@post(:id)&text=Hello

And Post author

@site(url)/inbox/?chat=u@user(:id)&text=Hello
