I/O Improvements Release
- snap pdf (phantomjs / headless chrome)
- write step to append new line to file
- table step to save table (no css selector)
- auto transpose datatable csv file
- support datatable cells with commas
- present() function to check element
- chrome extension note down element

Been holding back implementing some of these changes in order to avoid
attracting users. I’m happy with current user base, growing more and
faster will spread time thinly across much more edge cases needs.

Google just launched Puppeteer, I think most developers would be busy
now exploring it than other web automation tool, so I feel safe to add
these features now.
