PLUGINBROWSER make resumable

Browse source 
make the plugin browser remember the last item between invocations

this has bugged me for the longest time dealing with the plugin_menu

Fix a very old bug fix for reloading lang strings in the lang menu
FS#8117, sending multiple ENTER_MENU_ITEM callbacks from different
areas of the code makes it hard to keep track of where your callback
is originating
