[Yaml] Fixed double quotes escaping in Dumper
Issue #4308 is caused by Dumper::escapeWithDoubleQuotes() which uses [str_replace()](http://php.net/str_replace).
From the php docs:
> Because str_replace() replaces left to right, it might replace a previously inserted value when doing multiple replacements.
We should be very careful in deciding about the order of elements in $escapees array. I'd really appreciate if someone reviewed my fix. Tests say I didn't break anything but I'm not sure what percentage of Yaml specification is covered by tests.
Bug fix: yes
Feature addition: no
Backwards compatibility break: not that I know
Symfony2 tests pass: [](http://travis-ci.org/jakzal/symfony)
Fixes the following tickets: #4308

Something is really wrong with this method. You can see clearly that multiple characters would fail proper escaping.
Here's an example:
```
$value = '\\\\"some value\n \"some quoted string\" and \'some single quotes one\'"';
var_dump(Escaper::escapeWithDoubleQuotes($value));
string(72) ""\\\"some value\n \\some quoted string\\ and 'some single quotes one'\"""
```
To begin with the backslash - in the initial value you have 2 (escaped ones), that after escaping should result in 4, not in 1 (escaped). I guess this behavior has to be verified with the importer, but imho it does not seem right.
Does anyone know why this escaping wasn't done using a regular expression in first place?

Searching for https://duckduckgo.com/?q=what+is+\xc2\x85 the table on http://stackoverflow.com/questions/6609895/efficiently-replace-bad-characters is interesting enough to decide we need way more documentation on this file.
\xc2\x85 seems to be triple dot (ellipses)
\xe2\x80\xa9 seems to be paragraph separator see http://drupal.org/node/914360#comment-3468550

Apparently, some tests do not pass anymore after the patch. Can you have a look at them? Thanks.

Sure - looking into it.

I believe that's fixed.
The entire suite works locally now.
