Add support for adding "Child item" columns to list pages

[Nicklas Nordborg]

Support for adding "Parent item" columns was implemented in #2202. It should be relatively easy to extend this to also support columns with information from child items.

Changed the implementation of ParentItemColumn.getParentItems() to use the list transformation API instead of the annotation API. A "side-effect" is that this seems to be a lot faster.

Renamed some classes from "ParentItem" to "RelatedItem" to prepare for adding support for child items. Some other files and names in javascript and css has also been changed.

Implemented support for loading information from child items in columns, by adding an extra section to the column definition string: /ITEMTYPE/subtype-id/property --> /DIRECTION/ITEMTYPE/subtype-id/property.

DIRECTION can be either PARENT or CHILD. If not specified, PARENT, is assumed.

It is now possible to select child columns to display in the web client. The functionality has been enabled also for BIOSOURCE items. There is one issue with selecting columns from the RAWBIOASSAY level since it doesn't have a subtype. This can probably be solved by using the raw data type of platform instead.

Changed implementation so that sort order of items and values are predictable.

• Items are sorted by name.
• Other values are sorted by the name of the item they belong to.
