Alpha One

This is the second alpha of TKO.

It incorporates a number of changes, fixes a number of edge cases (particularly with the parser), and incorporates the last pre-release binding plugin, fast-foreach.

• Fix negation operator (-) application - integers/floats e.g. -1 work, as well as variables -x and expressions -(x + y)
• Use tko.binding.foreach for the foreach binding (based on brianmhunt/knockout-fast-foreach)
• Add each as an alias of foreach
• Parser
  • Correct behaviour with dereferencing members of expressions (e.g. (x || y).z or (abc || {x: null})['x'])
  • Fix canonical (() => ...) lambdas
  • Support C & C++ style comments (knockout/knockout#1524)
  • Fix filter/or ambiguity on pipe |
  • Raise an error with anonymous functions
  • Fix && and || operator precedence
• Updated Rollup - changes order of compilation, smaller output
• Fix issue with first rendering of an elseif binding
• Make the template binding expose a conditional for else-binding
• Expose ko.dependencyDetection
• Make sure obj.x uses this of obj where x is a function (e.g. click: model.onClick has this of model)
• Ensure obj.x only uses obj as this when x is a prototypal method (and not just a value)
• Honour explicit references to this (as $data)
• Ensure bindings with multiple filters work as expected
• If available, use a WeakMap for DOM node data (resolves knockout/knockout#2141)
• Fix filters not separated by whitespace (e.g. value|filter1|filter2)
