update build.json to refer to 'platform-dev'
No longer include platform in a polymer build!

Move polymer builds to build folder

Fix up test structure
Make resolvePath a little smarter

Use a "relative path" approach:
- if paths have common parts, make sure to not duplicate those parts
- if there are no common parts, just append

Inspired by the functionality of Node's path.relative
simplify CompoundPathObserver generator
docs.json
modify `instanceTemplate` for new MDV API (createInstance no longer takes syntax delegate as an argument)
PolymerExpressions methods are now on prototype instead of static
Remove polymer veiled elements system. Deprecated in favor of using ‘unresolved’ attribute, which is supported via platform.
Add bower.json
Correct expressions test so it properly uses tokenList filter.
fix path to use polymer.js in build folder
bump package.json for version
tests now import polymer.html
remove deprecated polymer.js, polymer should be included via importing polymer.html.
