v0.8.0

• functions: countTrue(bs : Boolean *) : Int = bs.filter(b=>b).count(). Function calls are automatically lifted to the correct multiplicity (like operators and built-in functions), and for incremental calculation function bodies are inlined at their use sites. Recursive functions are not supported.
• WebDSL eventual calculation is now concurrent, the number of threads can be selected at run-time.
• WebDSL backend features a 'flag all dependencies transitively dirty' to force recalculation of all values which influence some derived value.
