[Pharo-project] fulltext method search

I was bored today (after yet another kernel panic) so I implemented a quick fulltext search for methods. "this takes around 1.5mins" Search default buildIndex. "this is an instantaneous (~2ms!) search over all method sources" Search default matchSentence: 'Convert to a String with Characters' I think we should integrate that into some kind of "SpotLight" search for accessing the sources much much faster...
