Fix default value of php-auto-yasnippet-php-program

Set default path of Create-PHP-YASnippet.php in the same directory as
php-auto-yasnippets.el.

It does not need configuration when Create-PHP-YASnippet.php installed
in the same directory as php-auto-yasnippets.el.

Update documentation regarding ‘php-auto-yasnippet-php-program’

Commit bd4b7b34 introduces a better default value for that variable.
That patch alleviates the need for users to manually set its value in
most situations.  This patch updates the documentation in the README
and in the Elisp code to reflect the benefit of the new default value
for the ‘php-auto-yasnippet-php-program’ variable.
Merge branch 'github/pr/5'

Changing payas/remove-extra-whitespace to only remove whitespace.

This function no longer removes quotes and brackets from function
calls in the last parameter.

It also removes a trailing comma from the last parameter, if it
exists.

Some newly supported cases:

foo('quoted'  )
foo("quoted", )
foo($var,  )
foo($foo, bar() )

Bump the minor version number to 1.1.0
Delete the changelog

Lately I have been trying out different tools for automatically
generating a changelog, so eventually I will come back and recreate
this document.  But for now I am going to remove it since it is not
all that informative or useful anyways.
Clarify the meaning and purpose of the $snippet_chunks array

This patch contains no changes to any code, only comments.  The PHP
program creates and prints out an entire snippet definition.  However,
the strings within the $snippet_chunks array represent what the user
will see in Emacs, as the user will never see the full snippet
definition.  So the additional commentary helps make it clear that
$snippet_chunks is effectively the ‘public-facing output’ of the PHP
program we use.
