Added "Load Table..." functionality

This may need to be renamed, so I'll leave #24 open until people have
had a chance to play with this and leave their opinions.
- SetList was changed to add new event for "Load Table..." (Load w/o
format) button
- LoadedCluster_toSetList_v5 was given an optional input flag which if
set True only replaces device data and not columns.

This additional loading option will load Table data (text only),
variables, and user functions. All layouts/formatting/headers will
remain the same. It can only be used for identical device lists (same
Device class, each with same Column classes) between current SetList and
the target procedure.
Merge branch 'master' into improve-layout-portability

Conflicts:
	codes/SetList.vi

Conflict handled by doing a git checkout master codes/SetList.vi, and
manually adding the event case structure for the Load w/o Formatting
functionality.  Also manually added the UI button to the save/load tab on
the front panel.

Hopefully updates work on #24 to be merge-able, but should be tested
before putting on master.
