blocks: suggestion: make canvas split between blocks and code adjustable

[jaustin]

For larger programs, it would be nice to be able to adjust the proportion of the screen given to the 'text' part of the program and the blocks canvas

Even with some of the 'standard' blocks, the allocated canvas on my machine is not enough to avoid scrolling

There are a few options that come to mind

• a button to Show/Hide the code altogether
• Draggable 'divider' that adjusts the allocation
• (probably a bad idea) try to compromise between canvas and code based on the content size and window size

Yeah... that's on my todo list.

At the bottom right corner of the blockly pane will be a drag-able tag to adjust the width. Tested on Firefox and Chrome.

This took a while to figure out and in the end I went with a third party library for it. It would be hard to make the whole of the RHS border drag-able (rather than just the bottom right).
