When you filter say a list of systems, and click the 'select all' button,
systems outside of the filter (and that are not visible to the user within the
list pages returned by the filter) are added to set. Pretty much all systems in
the unfiltered list are added when the list is filtered. 

Tasks such as getting systems with a particular naming scheme into particular
system groups, or just creating on-the-fly system sets to perform work on, are
impossible to accomplish from the system list because of this behavior.

The checkbox in the upper left corner of the list does not provide the needed
functionality, because clicking that checkbox only selects all visible (on the
current page) systems, not all systems in the currently displayed list. (e.g.,
100-page list of 1,000 systems, filtered down to 20 pages of 200 systems. Click
on the upper-left corner. Following current behavior, that would only select the
10 systems available on page 1 of the 20 page list of 200 systems. Make sense?)

PROPOSED USE CASE to fix this
=============================

Scenario: Say I have a list of 1,000 systems, and I have let's say 200 systems
with the term 'wkstation' in their name. I need to do some work on systems in
this particular namespace, and only those systems. 

(1) I go to my system list. I get a 100-page list of 1,000 systems.

(2) I filter for 'wkstation' in that system list, and I get a 20-page list with
200 systems in it. 

(3) I hit the 'select all' button in the lower-left corner of the list-view 
because I want to add all of those 'wkstation' systems and put them in a system
group (or perhaps merely just want to work with them as a system set.) Only
those 200 systems will be added to my set.

(4) I then clear my set by hitting clear in the SSM bar, upper right.

(5) I then clear the filter by erasing the filter term and hitting the 'go' button.

(6) Now I see all 1,000 systems again. I click 'select all'. All 1,000 systems
are selected.
