Hide Google+ link under an article

The new Recent Posts uses Twenty Fourteen Ephemera widget in stead of
Recent Posts widget, so that Recent Posts HTML is as completely same as
Ephemera widgets.
Delete the title of the asides from Ephemera widget
Add excerpts in Recent Posts
Add an icon before the title of Recent Posts
Fix the header
Revert "Fix the header"

Because:
* The fixed fat line is ugly
* search-container toggle doesn't work

Expand line-height of the article & widget strings
Update Google XML Sitemaps to 4.0.3

Ephemera HTML is written by Twnety Fourteen theme, but Top Posts one is
written by JetPack plugin. I modified JetPack plugin.
Delete Jetpack_PostImages::get_image() for Top Posts Image List
Fix the link of Recent Posts is broken

get_post_format_link() doesn't support "standard", which is added by me.
Hide the author always at content-sidebar

With the default CSS, the author hides at the top page, but it shows at
a single page.
