Populate the table with workspaces that contain the same parameters.

The parameters should always be included in the table but not in the
log list. They should appear with values and errors (each a separate
column) and appear at the end of the table.

Add overwrite warning when creating a table. Make the list of log and
parameter files only populate with ones that are common in all runs.
Remove comments left in.

Populate the results table. Set up the select/deselect all buttons.
Connect some of the signals. Make a start on creating the table. Set
up a wiki page and have the help button connect to it.

Also, include .h and .cpp files for the new class that will handle what
the user wants from the results table tab.
