"Live Preview" rather than "Customize" after installing a theme

[nacin]

After installing a theme, we should use the terminology we decided on.

As the strings already exist, this is likely not an i18n-change.

"Live Preview" rather than "Customize" after installing/upgrading a theme. Props SergeyBiryukov. fixes #20784

Let's also add in a title attribute. We use __( 'Preview “%s”' ) in the list table.

Replying to nacin:

Let's also add in a title attribute.

Done in 20784.2.patch​.

For the upgrader skin when the theme is active, we hide these links. We should keep the Live Preview link, rename it to Customize, and ditch the fallback preview link.

In the network admin, looks like we properly hide the activate and preview links, but only for the installer skin, not for the upgrader skin.

20784.3.patch​ addresses the above suggestions.

We have __( 'Customize “%s”' ) on Manage Themes screen, so it's still not an i18n-change.

Looks good multi and single site, install and upgrade.

Post theme upgrade/install tweaks.

• Add title attributes to Live Preview links.
• Show Customize instead of Live Preview after upgrading current theme.
• Hide activate and preview links after theme upgrade when in the network admin.
