fixed getAttribute for array access with a boolean or float key
added changelog entry about fixed boolean array access
improved error message for non-existent or invalid attributes
refactored getAttribute

added tests for array access with confusable keys

array keys like boolean, numeric but string, floats, null
further improved exception message and distinguish array_call and any_call access
rename item to attribute in the exception message because that's the term that is used in twig, e.g. the  function
updated C extension accordingly
Adding a section about the slice filter

This code example shows how to loop over a subset of values in order to implement one common use-case of "break" in PHP. I decided to use the "full" notation of slice rather than the sugared version (that example would just be "for user in users[:10]")
Update striptags.rst
Adding link to slice filter per Stof's suggestion
