Updated polymer to v0.5.4

Update Polymer to v0.5.3 and bugfixes

• Updated Polymer to v0.5.3
• Fixed elements with checked attributes to be parsed as xml nodes
• Fixed bug with striping closing tags for elements nested into elements with selected/checked attributes

v0.2.5 Assets compression

• Component generator now generates separate .html, .css and .js files which will be compiled into single component file.
• Support of .css.sass and .js.coffee extenstions. Stylesheets and javascripts can now be referenced in html component simply as <link href="component.css" /> and <script src="component.js"/>
• Assets compression. Now stylesheets and javascripts are being compressed while inlining into component if rails config enables compression (like in production env).
• Support of relative paths. You can now reference component's css and js files either relative to /app/assets/components directory or relative to specific component directory (which means you can cpecify file name only if all component files live in same directory).

• platform.js -> webcomponents.js. Be sure to edit your application.js manifest to require polymer/webcomponents instead of platform polymer/platform

v0.2.3

• Updated Polymer to 0.4.1
• Search for components in assets paths, as was discussed in PR12
