Fixed up some of the admin/extensions/plugins.php stuff to do with
artefacts & blocktypes and their interdependencies.
(there's still a todo in there but it's cosmetic).

Disable the add/remove column buttons when they are not allowed to be used. Removed the removing of the remove column button when only one column is left.

There is one bug with this stuff, caused because the new columns returned have the incorrect columnsN class. If all but one column is removed, then a column added to the left hand side, then you try adding a column to the right hand side, a javascript error will occur. This will be fixed when the correct data is sent back from the server.

Use view_build_column to return the HTML for the new column when a column is added. Renamed a method call to match the change in viewlib. Added what I'm going to do next to the comment.

Implemented adding a column. The steps involved are documented in the method. There's one small hack to make sure the new column has the correct 'columnsN' class, which will not be needed when adding a column is implemented in the backend.

Use the viewlib functions for building the column HTML. The data has been moved to viewlib.php also.

Added functions for generating HTML for columns. Renamed a couple of functions also to have the consistent 'view_' function naming schema.

moved all the STATEMENTs out of install.xml into postinst, split postinst into two - right after core data & right at the end

More progress on the views frontend. There are stubs for several actions, and javascript implementations of those actions.

With javascript, an AJAX request is made to retrieve the new blocktypes. Without javascript, a standard GET request changes which one is displayed. When javascript is on, the radio buttons are not sent back.

Currently contains a bunch of hardcoded data that needs translating into api calls, a javascript overlay file for the rich UI, a CSS file for laying out the UI page, a smarty template for the HTML, and a metric ton of work still to do.

removed all upgrades previous to the last minupgradefrom... this means we can get rid of the previous view template upgrades

Added a missing language string about javascript not being enabled. Will be a good day when we can remove this string\!
