[Ayatana] Dash "More Apps" and "Find Files" options are redundant

[Matt Richardson <m.richardson.1990@xxxxxxxxxxxxx>]

With the inclusion of the Applications and Files lenses in the dash, the 
two buttons "More Apps" and "Find Files" on the initial view of the dash 
are somewhat redundant.

Perhaps a better use of these buttons would be "Office Apps" and 
"Settings", with each behaving similar to the "Media Apps" or "Internet 
Apps" buttons.

This would make it easier for new users to find commonly used software 
(office) and find how to change settings.
