Event parameter renaming in internationalization

Patch Set 2 notes:
* In language_switch.js, commented out console.log calls that were
  preventing code generation tests from passing.
* In lexical-variables.js:
  + In local_variable_statement.renameFree, changed buggy nondestructive
    bodyFreeVars.difference(localNameSet) to correct destructive
    bodyFreeVars.subtract(localNameSet).
  + In lexical_variable_set, fixed incorrect typeblock

Patch Set 1 notes:

This commit makes several substantial additions/changes to the
ai2inter branch, but almost all should be merged into master as well.

* The renaming code in blocklyeditor/src/field_lexical_variable.js has
  been substantially cleaned up and generalized. When renaming a
  parameter from and old name to a new name would naively lead to
  variable capture involving the new name, there is now a choice
  between (Strategy1) changing the new name to avoid capture and
  (Strategy2) renaming internally declared variables to avoid capture
  of the new name. The latter strategy is essential in cases like
  renaming an event parameter, where there is no option of changing
  the new name.

* Strategy2 is implemented by methods renameBound, renameFree, and
  freeVariables defined on blocks involving variable declarations or
  references. These are implemented in terms of two new kinds of
  objects: NameSet (defined in blocklyeditor/src/nameSet.js) and
  Substitution (defined in blocklyeditor/src/substitution.js)

* This code correctly handles the renaming of event parameters when
  switching languages in internationalization. So if a Canvas.Dragged
  block is changed to Chinese, not only will the declaration of
  "startX" change to the Chinese equivalent, but all references to
  "startX" will change appropriately as well. It even correctly
  handles the case where a local English variable "startX" is
  introduced between the Chinese declaration and uses of "startX".

  All of this magic requires (1) XML mutation attributes "eventparam"
  for getters and setters of event parameters and (2) a special case
  for blocks of type component_event in Blockly.Xml.domToBlock that
  does the appropriate renaming. sh

* In various blocks definition, the category field was changed from
  abstract categories like Blockly.Msg.LANG_CATEGORY_LOGIC to concrete
  ones like 'Logic'. The abstract versions DO NOT WORK in the current
  system.

These "localized" operations are used in the internationalization code
They are provided by the browser in the actual system, but
are not present in phantomJS.  So define mock versions to be used by the tests.

Internationalization for AI2

Added Internationalization support
Added/Modified renaming of procedures so they work with internationalization

Note: Commented out language menu until we have a clean Chinese translation.
