Quotes don't get converted to HTML entities inside <textarea>

[sir qwerty]

Quotes (both single and double) get converted to HTML entities correctly when typed inside block elements such as DIV, P, BLOCKQUOTE, CODE and so on.
<p>'a'<p> is converted to <p>&#39;a&#39;</p>

Unfortunatelly they are ignored when typed inside TEXTAREA element:
<p><textarea>'a'</textarea></p> stays untouched. Obviously this breaks up my later executed SQL statements. Ampersands get converted OK.

Securing the quotes during PHP process would be a workaround, but till now I've always relied on this CKeditor's function.

ACF is turned off (config.allowedContent = true;) everything else regarding entities is set to default values. Worked fine in V4, maybe got broken with deeper ACF implementation.

Windows browsers: IE 11, Chrome 31, FF 25.

I was able to reproduce this from CKEditor 4.3 in every browser.

Pushed to ​t/11250 at dev and tests.

I was thinking about adding tests for these entities to test process textarea in htmldataprocessor.html

with following code:

assert.areSame( os + '"' + oe, toHtml( ss + '"' + se ), 'textarea processing did not convert double quote to entity' );
assert.areSame( ss + ''' + se, toHtml( ss + '\'' + se ), 'textarea processing did not convert single quote to entity' );

But function toHtml() seems not to use all the goodies which editor#setData does. I ended up with adding them to separate TCs.

Test should be added to dt/plugins/entities, since they test that plugin.

TCs moved.

Pushed one additional commit to tests.
