Feature request: expand/collapse all folds

[daveyarwood]

Hi, thanks for the great plugin! I use it all the time.

One thing I keep finding myself wishing I could do, especially on large files, is click a button that will collapse every fold so I can get a "big picture" view of the file. Then I could click the button again to expand all of the folds.

In the console:

for (x of $$('.collapser')) x.click()

For v0.3.3, it is now:-

for (x of $$('.gcf-collapser')) x.click()

It would still be useful to have this as a shortcut.
