Reorder "action links" on chrome://extensions

Reorder "action links" on chrome://extensions

Move the Options, Permissions, Visit website, Launch, and
Reload links to be on the same line in the
chrome://extensions page, directly below the description (so
they are in the same place for all extensions in the list).

Also reword "Visit website" to be either "Details" or
"Developer website", depending on whether it will link to
the developer's website or the chrome web store.

Finally, tweak the css to give a bit more padding to the
description and make the version text grey.
