[PD] [entry] changes

Hey all,

The netpd project's chat interface inspired me to fix up the [entry]
object so that it could serve as the building block for a chat app.
I've added a number of improvements:

• fixed fg/bg color bug
• created [add( message which allows you to add to existing text
• added float support to [set( and [add( messages
• created second outlet which outputs the keys as you type them (this

makes it easy to assign the enter/return key to make the box send its
text).

• made the inlet visible.
• added rudimentary [size x y( message

There are a couple of things that I think would be worth adding:

• a message to add one character at a time
• messages to change the font face, size, and weight
• messages to change the border of the box

This is in today's auto-builds if you want to try it.
