spider searches $available_controllers which now also contains models stored in the modules folders. Crashed because there was no isSearchable() method, so I added it to expRecord. Also the Twitter model was extended to use expRecord (not sure if this will cause other problems, if so, just add an isSearchable() method). Also a disconnect in textController. Is says it is Searchable, but set to return false when getting spider content (made an assumption that search operated like in 1.0). I commented out the addContentToSearch() method, so it works per expRecord. If this is not desired, uncomment it out and change isSearchable() to return false. Also corrected a recent typo in the exponent_modules_list() function.
