added "init-size" tag to <bg-pane> decorator

[ryan-schroeder]

I needed this for my project - I need to be able to set the initial size of the panes (awesome code btw, thanks for this tool). To prevent conflicts, the tag is only allowed on the first pane, not the second.

No worries if you don't like this, I can just use my own fork for my project.

Did you solve the horizontal scrollbar on bottom? It appears in all 3 browsers

nevermind, found it... there's a "padding: 10px" on index.html causing the problem

Yo! Good catch, I didn't think about the index.html example.
