Some cleanups and attempts at improving code-readability and -extensibility:
* added inner holder class to BreakingAlgorithm to contain everything related to the fitness classes. Improves readability of both the code and the trace messages.
* extracted blocks of code in BreakingAlgorithm.findBreakingPoints() into protected methods. Following the already existing handleBox(), added handleGlueAt() and handlePenaltyAt() to provide extension points to subclasses. Extraction of the code-blocks related to the node-recovery mechanism.
* extracted blocks of code in BreakingAlgorithm.considerLegalBreak() into protected methods: deactivateNode(), activateNode() and forceNode()
* factored the functionality to obtain the index of the first box into KnuthSequence... just seemed to make sense; may be useful elsewhere.
* some (but not all :() javadoc fixups
* minor changes to LineLayoutManager and PageBreakingAlgorithm to take into account above changes

First very rough implementation of Changing IPD. It works only with (possibly nested) fo:block elements containing pure text. Doesn't work if the page break occurs /between/ two fo:block. There's a problem with elastic spaces that get lost after the ipd change. There is duplicated code especially in BlockStackingLayoutManager. Plus probably plenty of other issues...

My bad.. copy paste error I introduced which broke forrest.

Fed up with all those trailing whitespaces. Let's remove them all (once... and for all?)

Changed the way overflowing pages are handled. The overflow property on region-body is now used to define the behaviour. It removes the "Some content could not fit..." exception that bugged so many. However, the change does not yet change any keep behaviour.

Content in block-containers makes better use of shrink to fit content vertically into the available area. This can be used indirectly to justify content vertically in a block-container.
PageBreakingAlgorithm now writes to a different logger than its base class. Makes debugging easier.
Some minor logging improvements to improve clarity.

Attempt at providing context information about the element causing an endless loop because of an area overflow in b-p-direction. This should make the error message more helpful.
The overflow property is not yet implemented, so at the moment if wrap-option = "no-wrap" and the text overflows it invades the margins.

I had to modify BreakingAlgorithm to add best records for parts which are too short.
Furthermore, it took an additional computed value to tweak the balancing. It effectively makes shorter trailing parts preferred.

Page breaking process now respects changing available BPD (not IPD) over multiple pages.
PageSequenceMaster allows backtracking.
PageViewports are delivered through a PageViewportProvider class which caches PVs and handles cases where the breaking algorithm allocates PVs that turn out to be unused later (because of hard breaks which may cause blank pages, for example).

Merge of branch Temp_KnuthStylePageBreaking back into HEAD.
Temp_KnuthStylePageBreaking branch and HEAD have been tagged prior to the merge, so merging uncommitted work from the branch should be easier.
