Update Companion Error Reporting.

Arrange for block load errors to be reflected back as red triangles,
with messages, associated with the block that caused the error.

Runtime errors are now reported back to the blocks editor as well as
being displayed as a “toast” in the Companion. Note: Such reports are
throttled to once every 5 seconds to avoid a flood of errors when the
error occurs in an event handler that is called frequently (like from
the accelerometer).

Updated the Companion Version to 2.07nb7. Version 2.07nb6 is still
supported (with no new functionality). Older versions are no longer
supported and will result in an upgrade required warning.

Fixed type error in generator for split-at-any and split-at-first-of-any
Fixed the bug in split-at-any and split-at-first-of-any where they
could not handle patterns containing character with special meanings
in regexps.
Added unit tests for the split commands, and extended the
unit test framework to handle blocks with dropdown operators.
Created a separate class for Blockly Code Generator Tests.
Changed split (only split, not splt-at-any, etc.) so that there
is no trailing empty-string in the result, when "splitting" at the
final character in the string.

component block generation change

There is now only one Blockly.Language object for the different types
of component blocks (events, methods, get/set, component literal). The
component blocks are differentiated by the information inside of the
mutator xml tag (component type, instance name, method/event type,
generic or not).

All set and get blocks for properties are now visible in the drawer.
