Partially inspired by hanya's work.

Restore previous comment now that long_path.patch is back.

IndexWriter.MaxFieldLength.LIMITED caused terms to be silently dropped 
after the 10,000th term in a field. Switch to UNLIMITED which doesnt casue 
this to happen.

This patch was left out from the lucene update in r1337602
and apparently has an origin in BZ #i109096#.
No one so far seems to have noticed negative effects but
after consulting in ApacheConEU it seems a good idea to
keep it.

Special thanks to Steve Rowe.

#i121442# - Add a StatusbarController example replacing the existing ".uno:ModifiedStatus" in Writer

#i121442# - framework refactoring and new code to support status bar merging and UNO StatusbarControllers

Modify the current StatusbarController API so that it can be used by pure UNO implementations.

In the current implementation and its API design, it is impossible to
implement a StatusbarController in UNO, because there is no way in UNO
for the controller to manipulate its status bar item; the current
implementation of UNO based StatusbarController have to access directly
the VCL StatusBar through the AWT XWindow in order to manipulate its
item.

Designing an API that wraps the VCL StatusBar does not make sense: a
StatusbarController should only have access to the status bar item it
controls, not the whole status bar. Therefore this new interface
represents only the functionality of an item in a status bar, to be
controlled by a StatusbarController.

A StatusbarController that draws its status bar item may need to draw a
graphic representing the feature state. css::awt::XGraphics API should
be extended to include VCL's OuptDevice::DrawImage.

A StatusbarController that draws its status bar item may need to trigger
a repainting of its item when the feature state changes. Currently, the
only way to trigger this redraw is by changing the item text or the item
data, so that the vcl implementation calls ImplDrawItem; this is rather
implementation-specific.
