Implement a generic selection component

[thejonan]

Take the existing selection mechanism and wrap it as a generic skill-set. Few things are important here and need to be clarified:

• It is important to have the (de)select mechanism in-browser, so the user doesn't need to wait for a server response to see the effect of her selection. However, certain storing of selection may be need on the server, still - no need to wait for it.
• Currently the page's URL is changed on every selection so that sending the current URL also sends the selection. This has some additional problems, however. Probably it is a good idea to encapsulate the in-browser navigation possibilities in a separate skill-set (Implement a generic in-browser navigation skill-set #9).

From the perspective of the work made, the best possible approach is:

• Have a urlBasketParameter configuration, so the skill knows where to take the selected IDs from.
• Handle the afterTranslation callbacks and fill whatever possible of the listed IDs.
• Provide the onOpen handler, so when combined with something like TabExpansion - Create TabExpansion widget #16 - can react on opening, and if still there are unmatched entries (only their IDs) - use the Spying skill from SolrJsX to launch a separate query for the remaining ones.
