selenider 0.2.0

New features

• elem_select() is a new function for interacting with <select>/<option>
  elements, allowing you to easily select by value, text and index.
• New current_url() returns the URL of the current page.

Major changes

• Previously, selenider used RSelenium
  as a Selenium backend. However, this package did not work with the latest version
  of Selenium, or the latest version of Google Chrome. It now uses
  selenium, which is compatible
  with both. This should make selenider more reliable, and more likely to
  work out of the box when using Selenium.
• Printing HTML elements now prints the actual HTML contained by the element.
  Previously, it printed the element in "lazy" form, describing how the element
  was to be obtained. While this new change makes viewing elements much easier,
  it also means that to print an element, it needs to exist in the DOM. Use
  print_lazy() to use the previous behaviour when printing.

Minor changes and bug fixes

• take_screenshot() with file = NULL now views the screenshot correctly.
• elem_set_value() now correctly invisibly returns its first argument x,
  allowing it to be used in a pipeline.
• find_element() and find_elements() no longer accept the link_text
  argument, as this was not working with chromote. Use elem_find() or
  elem_filter() instead.
• elem_get_value() now uses the JavaScript value property of an element,
  not the "value" attribute, meaning that it works in more cases.
