Commit 46 (post beta)
New features and improvements:

- New {{props}} tag to iterate through fields/properties of an object:
  {{props}} {{:key}}:  {{:prop}} {{/props}}
  See http://borismoore.github.io/jsrender/demos/scenarios/03_iterating-through-fields-scenario.html

- Use of #index in a nested context (e.g. in an {{if}} block) now produces
 (in debugMode === true) a warning error indicating getIndex() syntax.

- (BREAKING CHANGE)
  Overriding of global helpers, templates, tags or converters:
  > resources specific to a template (e.g. a helper in the template’s
  helpers collection) now override resources of the same name defined
  globally (e.g. using $.views.helpers("myHelper", ...); ).
  > Helpers passed in as options override both template-specific and global
  helpers of the same name

- Several bug fixes

- Many new unit tests
