Update on join for events. Still not functional. Noticed errors on evts connection management for detecting incompatiblities on attributes

general code review

seperate searching result to differnt tab, fix bug of events; split component's name before searching

add 2 icons on menu bar; change address to check connection; change notification's content;  add name for search dialog; add text in search field for  selected block

#add Dialog Search ; #add option 'External Search' in popup menu; #handle multiselect component for search ; # add Googe crawler and parse in GoogleSearch.java in myutil; #add external library jsoup-1.8.1.jar in bin ; # edit Makefile in order to compile with the library # ! Error: cannot find the library on runtime

Edition: bug on mouse corrected
