Allow user to supply all naming and pathing references [#1361684]

I'm not sure how many times I've had to yank the blog module from core, do a (mostly) global search and replace, clean up the remaining tidbit references to "Blog," just because a client wants the exact same functionality, but doesn't want it called "Blog." So....

This feature request is for configuration settings in the blog module itself to allow a user to supply all naming / pathing references.

Example differences if the user wanted Blogs to be listed as Articles:

Blog => Articles
{Users}'s blog => {Users}'s Articles
/blog/2 => /article/2

Best,
Sam

PS: Yes, you can mostly do this with String overrides and URL aliases, but it's definitely not easy. Here's some of the stringoverrides for example:

!name's blog	!name's articles
!username's blog	!username's articles
Blog	Articles
Blogs	Articles
Create new blog entry	Create new article
Post new blog entry.	Create new article
Read !username's latest blog entries.	Read !username's latest articles.
View recent blog entries	View recent articles
You are not allowed to post a new blog entry.	You are not allowed to post a new article entry.
