Terminology for "Front" and "Home"

[WraithKenny]

The following related tickets all have discussions concerning the Terminology for "Front Page" and "Home Page" is some way.

#16379 - Better UI for doing "Page on Front"
(UI effected by the terminology)

#10158 - Deprecate is_home() and is_single(), in favor of is_blog() and is_post()
(Conditional Tags effected by the terminology)

#18705 - home_url() and is_home() with a static front page
(URL function effected by the terminology)

Additionally, Template files are effected by the terminology (home.php and front-page.php)

This ticket is intended to discuss the best options that address the above terminology concerns for the sake of consistency and usability. If a determination is made here, hopefully we can use the terminology to inform the above tickets.

Regardless of the name of the is_home() function, I am proposing adding an additional conditional tag called is_blog_page() to return true if any of the blog-related pages are currently being viewed. The name of that function could change to match any changes to the name or implementation of is_home().

I've submitted a patch with ticket #21620.
