jsre:

- require became loadScript(), no require is supplied
- bignumber_js.go: heredoc v2.0.3 minified fixed for otto Regexp incompatibility https://github.com/robertkrimen/otto#regular-expression-incompatibility
- bignumber.min.js also updated in mist/assets/ext
- ethereum_js.go: latest master minified
- assetPath in constructor
- Eval/Exec/Handle/ToVal nice API
- jsre tests
