[Rails-devel] StockRound changes

[Erik V. <eri...@hc...>]

I have committed the following changes:

- The StockRounds now also use PossibleAction objects as an
interface between UI and back-end. New PossibleAction subclasses
are BuyCertificate and SellShares. These allow selling or
(if in the brown zone) buying multiple shares by one action
(this also was an outstanding feature request).

- The StockRound UI has changed somewhat. The choice of the
number of shares to sell/buy can be indicated in a selection popup.
If there is no choice, this popup is replaced by a confirmation popup.
The Sell and Buy buttons, now being redundant, have been removed.

- Buttons now use ActionButton, a new subclass of JButton. 
ActionButton allows attaching a PossibleAction object, 
that will be sent to the back-end (representing the action to be executed). 
This is similar to what we already had in ClickField (a subclass of
JToggleButton).

- The now much more loose coupling between front- and back-end
should allow for easier changes to the UI or new versions of the UI.
