Call launchGetThemesWebView if ActivityNotFound.

Themes Showcase may be installed but disabled by the user.  If this

Hardcode 'Get More' entries

Previously entries were populated from the wiki causing:

(2) The wiki caches articles and can cause changes to not be updated quickly enough.

So until this is fixed we will stick with hardcoded entries in the strings.xml
