Columns in search result should be reordered

[saberraz]

At the moment, the less informative columns appear first.

also, the plugin should remember the columns' width

Hi guys,

Was thinking a little about this one - I think rather than handling column ordering through the configuration interface, this should be handled via the results table by allowing users to drag/drop reorder the columns and also change their width.

When anything is changed, the column settings would be saved via QSettings - this would also mean that the column ordering and width could be deployed to users via a registry patch for larger deployments.
