Allow users to deselect algorithm categories they are not interested in

[Nick Draper]

This will need to be another option on the Preferences window to list all the categories with a mechanish to remove those that are not interesting (checkboxes?).

The users selections should be stored in the user.properties file.

At the moment the only way to get a list of categories is to ask every algorithm, a method should be added to the Algorithm Factory or Manager to provide this list.

(In [12684]) fixes #2126, refs #2128 Multiple categories are now correctly displayed in Mantidplot. Hiding of categories is implemented for Mantidplot, but no GUI to select yet. hidden categories can be set in the properties files with algorithms.categories.hidden

[Nick Draper]

(In [12695]) fixes #2127 Python supports multiple categories, no work really as python does not realy support categories any more.

refs #2128 Python and the mantidplot UI respects not showing algorithms if all of it's categories are hidden

GUI implementation of selection moved to #3207.

This ticket will record just the technical implementation of hiding and allow that to be tested.
