Settings: Fix ambiguous expanded desktop options

Currently, one may interpret "With status bar" as both:
1. With the status bar also hidden
2. With the status bar left untouched

And vice versa with "without status bar". This patch aims to make it
more clear-cut.

Patch Set 2: Re-worded as per David van Tonder's suggestions.

Settings: Simplyfiy expanded desktop summary

There is no need to have an extra summary string to display the
state of the expanded desktop mode. This commit removes the unneeded
strings and uses the entries as summary.
