CommandFactories not holding their weight

For the last two years I have been teaching the uDig training course and one of the "mistakes" I highlight year after year is the various "factories" used to make commands.

The original plan here was to have several visualization technologies; and allow these technologies to punt out commands to perform common tasks (such as zoom in). Since this has not materialized the factories represent an extra level of complexity that is not paying for itself.

This bug tracks the removal of factories form the application; an application of the "Code it like you mean it" rule.
