[dev] Help links

[Duck]

I would like to change the behaviour of Help link in the menu. Currently we 
are displaying the link to the help pop-up window that renders the help.xml, 
that is mainly not translated. I would like to see this link to drive the 
user to a WIKI page, as pages can be modified by the support team without 
administration intervention (or even by advanced users). We should allow to 
pass the link the the wiki, on which is will be append the AppHelp string 
(example HermesHelp). With this we can use the site wiki or a common wiki 
pages or a general help render page like prefs to render this page with the 
original application menu on the top.
