no issue
- Removed deprecated 'blog' reference from frontend data. The alias (site->blog) stays till next version (v4) as it's not leaving much of technical debt but would ease the migration process for anybody still using it.
- The follow up to this is substitute of all references to `options.data.blog` with `options.data.site` in "frontend"
- Fixed test utils helper to use `site` instead of `blog`
- Removed 0.1 flag checks in {{get}} helper
- Removed user aliasing from {{get}} helper
- Removed unused translation for {{get}} helper
- Added a note to excerpt changes in metadata for future reference
- Removed page alias used in description helper. The mix of page context with post object in the metadata was only possible in v0.1
- Changed mock in ghost_head helper to use v2
- Removed unneeded test for body class helper
