[drupal-docs] Reword these messages please

[Karoly Negyesi]

Hi!

Some messages in the code needs better wording. I specifically know two  
that I have written.

'It appears your host is not configured correctly for Clean URLs. Please  
check for <code>ModRewrite</code> support with your administrator.'

this resulted in much confusion -- when ModRewrite is on but the  
configuration is such a one that the rewrite rule we supply with Drupal  
does not work then people say 'hey i have modrewrite on'.

'Your settings are not saved because of the errors above'

uh, this sounds odd. yet it is necessary -- the problem here is that with  
forms API , the admin/settings screen does not save if you have any error,  
for example, you lack the files directory which is pretty common. And  
there is no indication of the fact that the form you see below is not  
saved. So a message is necessary but it needs (much) better wording. Also,  
because the settings form is a very generic one, a gazillion of admin  
forms are rendered using this function, loose the word 'above', as it is  
possible that some errors will be displayed below this message.

If something is not clear about these messages, feel free to contact me in  
person, on IRC, here on the list, I am happy to help you, but these  
messages should be understandable very soon now, ie. before 4.7RC.

Regards
