This adds the ability to provide a third argument in the column
definition ("name", "type", "extra"). Extra columns will not be shown
by the CLI by default, but can be seen by passing an empty list to the
CLI (ie, provide no parameters to the `--columns` flag). Otherwise any
columns passed to `--columns` will be displayed and no other columns
will. If no valid column name are passed to columns, then the normal
list of columns (not including extra) will be displayed.
All other UIs will need to implement support for the extra column,
otherwise they will silently ignore it.

There's now the ability for plugins to say whether a particular column should be displayed or not (although this is for the UI to decide how to interpret). The plugin will still output all data, and it's the UI's job to decide what the user sees based on how it decides to display the data. The CLI will now display all columns except those marked as extra within the plugin (by creating a column with a third boolean parameter set to true). This means that the tree grid is still defined early and ideally should not be altered between runs of a plugin. To display all columns, pass in I'm still not sure I really like this, I skirted actually implementing renderer options because it would be a lot of work to define them properly, they need to be able to take in user input as well as pass data from the plugin itself in this instance, and it would probably have a significant impact on plugins, whereas at the moment this is quite minimal. Still uncertain about the whole thing though (and the way of displaying all columns in the CLI is a little awkward). The good news is it shouldn't impact any other UIs at all. |

Minor API bump
Slightly heavier weight classes rather than tuples, but allows greater flexibility and future assignment of new attribtues.
This adds support for selective column output on the CLI. Other UIs are welcome to implement their own features. Still to add to this is the ability for plugins to provide their own list of expected columns (currently, all columns are output by default).
