XWEEKACT-13 Deduplicate project list in project suggest (Add Done/Planned Activity)

In this document "WeeklyActivityCode/SuggestAjaxPJ" : I make the following modifications : 
1) I modified the XML response. Now the response return for each project, its title that will be displayed in the suggest picker input and the project docFullName that will be saved in project  property of the WeeklyActivityCode.DoneActivityClass object
2) I remove the duplicated values from the suggest picker

In this document "WeeklyActivityCode/Macros" : I make the following modifications : 
Added a hidden input that will contain the projectDocFullName after the selection of an item in the suggest picker. As showed below : 
<input type="hidden" value="$!pValue" name="${pSuggestHiddenName}" id="${pSuggestHiddenName}"/>
Have you tried building your project? Running a simple `mvn clean install` on the project will clearly show that this document is not well formatted.

Please see the coding style for XML documents [XWikiXMLFilesCodeStyle](http://dev.xwiki.org/xwiki/bin/view/Community/XWikiXMLFilesCodeStyle) and make sure you run `mvn xar:format` every time before committing any changes you have done to a xar project/extension.
