[Plone-i18n] Plone translation

[Houda L. <ho...@si...>]

 I and Ofer Weisglass  are working on the arabic translation Plone  , so
we found some problems:

first,there  are values that we can see on the plone portal in english
but they are not on the po files, i checked all the po files 

for exemple: in HTML settings(control panel), there are buttons named
'nasty tags' and 'removed selected items' ,'add custom tags' ,'add
stripped attributes'...
other example : in Markup settings , values of check box
(text/html,text/plain....)

Second , i translet some values but they are not Oand visible in the
portal plone for exemple :
add event => Event Location  , Event Starts , Event Ends

There are screenshots of the plone in arabic in this link
