0.2.0

• better choose the initially selected symbol: Instead of choosing the nearest symbol, typically prefer the symbol right above the current position.
• tune fuzzy matcher: The original matcher was written to choose from a set of simple tokens. Here, in our context, we need to match against full lines which obviously contain whitespace and punctuation. Try to move the algorithm in that (unusual) direction.
• add simple double-click binding which acts like pressing enter while on the clicked line.
