v1.0.8 release

Feature improvements:
  - Improvements (and associated bug fixes) when converters return arrays.
    With minor breakng change for some advanced scenarios:

    Converters which return arrays now have an improved heuristic behavior
    to determine whether to return the array (retArray) as value for the
    first argument, or as an array of values for multiple bindTo/bindFrom
    targets.
    (If bindTo/bindFrom is an array of length l, l > 1 and the converter
    is returning an array retArray of length l, then treat retArray as an
    array of values for the multiple targets bindTo/bindFrom targets)
    In addition the heurisic default behavior can be overidden by setting
    retArray.arg0 = true/false.

    See http://jsviews.com/#tagoptions@bindto
    and http://jsviews.com/#hierarchypatterns@picker-multi

Several bug fixes, and code improvements, particularly for data-linked
<select> tags (including multiselect), and {{checkboxgroup}} tags:

  - #450
    multiiselect not updating when linked array changes

  - #449
    If the selected value of a data-linked <select> is set prior to adding
    options, selection is not always established correctly

Additional small corrections or improvements to documentation, and some
additional unit tests...
