component styling update:
- support nested @host syntax @host { * { /* declarations */ } };
- support inherited @host rules;
- add support for pseudo scoping selectors when scoped stylesheets are unavailable
g-selector: fixes bug using multi; last selected item may now be unselected by clicking on it.
g-panels: now supports a user supplied transition component.
component styling workbench test
add responsive class directly on g-menu-button
g-panels: allow panels to specify they are custom to avoid application of extra layout styling (e.g. 100% width when responsive)
