(still default enabled, but now it's save to use the OS X defaults without bothering about it)

Up to now, notification of invalidated subareas was available for controls
but yet, the layout always ended up being totally rebuilt. For instance,
 a small animated image meant a total rebuild of everything. For simple skins,
 this could go unnoticed, but old computers had much difficulty with more
 complex skins (e.g wmp11), that were mostly busy rebuilding layouts
 over and over.

This patch ensures that only what needs to be rebuilt is rebuilt. Some skins
 like wmp11 on Linux do show dramatic improvement with this one patch.

This patch does the following:
   - fix skins that could not be saved, because their ids contained the space
     character. Names are now enclosed between "" to preserve those spaces.
   - show windows only when the init and check work is done. This avoids
     fleeting windows that sometimes occur (usually visible on Linux)

Local paths are more user-friendly for display than full uri
when that makes sense

This patch is mainly intended to work out the async queue getting
bigger and bigger when skins cannot keep up with command processing.
Since flushing the queue is an infinite loop, this ends up in vlc
hanging (frozen GUI). This happens when skins are complex (many controls,
many timers, animated images, scrolling text, ...)

With this patch, new commands of a given type can now replace pending
commands not yet processed when that makes sense (e.g position, volume, ...).
The position is really the one responsible for overflooding the queue.

Handles "\\hostname" properly.
On Windows, error out on "X:directory" instead of aborting. Looking up
the current directory of the specified drive letter would be a better,
though.

text controls were far from being optimized
   - a notifyLayout was executed at creation of text control, leading
     to rebuilding the layout twice.
   - the init of the variable was done after the control was created
     which means still more rebuild of the layout.

This patch ensures that no rebuild is done at init since we are already in the
process of rebuilding the entire layout.

only refresh position if the value really changed w.r.t the control measure unit.

When an item gets sub-items, we have to run our own random-picking among
the new items.
