update to post template on twitter theme: added dynamic page description
added dynamic tagline to posts and conditional display statement on partial view
Fixed a malformed date in the sample post.
Fix that theme will not be overwritten if exists.

When some theme exists, "rake theme:install" will not overwrite the
previous theme files, even if we answer "y" to the "Do you want to
overwrite?" question. This commit fixes this.
Giving every post/page the "smarter" custom tagline (just like page.html in master branch).
P.S. In master branch, every page has "smarter"  custom tagline but every post haven't.
