Refactor tree views and improve consistency

Created by: riyad

• rename _tree_file to _blob
• extract _blob_actions from _blob and also use them in the blame view
• fix blob actions to only show appropriate actions
• extract partials for rendering different blob contents
• replace file mode with file size in file views
• clean up TreeDecorator
• make buttons in titles of tree and file views look alike
