Upgrade to latest TypeScript master (1.4) code

* fix regression in builder behavior (building downstream projects when
doing a full rebuild - which causes unnecessary building and errors to
temporarily show up). this isn't the best fix but its back to the
previous behavior before recent changes
* fix NPE in QuickInfo
* add new script element kinds (and fix the name of "const")
* call just "jake local" since the declaration task is now on by default
