Add consistent links to plugin/theme page in the directory

The "WordPress.org Plugin Page" link placement is unintuitive. Could we link the plugin title instead?

• ​https://translate.wordpress.org/projects/wp-themes/twentyfifteen

No link to the theme page at all. Could we link the theme title?

In 2863:

Translate, Theme Directory: Append the URL to the directory to the theme description.

Fixes #1409.

I still think the current link placement is not really intuitive.

Could we link the project name instead of (or in addition to) piggybacking on $sub_project->description?

meta-1409.patch​ is untested, as WordPress Meta Environment still has the old GlotPress without any projects, and I can't figure out how to log in there.

The link belongs to the description which is consistent with other projects. Linking the project name in the box would be inconsistent.

Consistency is a good point :)
