[TYPO3-project-4-3] saltedpasswords for v4.3

[Steffen Ritter]

Hi 2 all,

just wanted to inform you about the "ongoing" progress:

 > * remove the "suggestions" in ext_emconf.php
 >  -> only rsaauth is suggested, the others can be removed

done

 > Steffen and me (it's like Steffen²) came over to use a userfunc in 
ExtMgm checking this, and make the user really clear by a message if 
saltedpasswords is activated in be or why not exlpaining the reasons to 
users who are not into the topic.

I implemented this...
You'll find this in classes/class.tx_saltedpasswords_emconfhelper.php
Would be glad if you would have a quick look (and testing). Afterwards 
tell me:
Are the texts ok, should we localize them, are there any configuration 
combinations or hints we in addition should provide to the user.

 > Second: in the EM configuration forceSalted and updatePasswd are 
selected by default, but updatePasswd don't work together with 
forceSalted. This looks very odd to me.

a Warning will be displayed to the user to inform him.

Since #10017 has been committed, the hook for felogin is present too.


In addition i renamed some function in _div after an proposition from 
Marcus Krause.

Have fun testing the new features. I'm glad to here any comments.
Looking forward to have saltedpasswords in beta1

regards

Steffen
