- rename failure code to status code, and add more to handle
cancellation.
- change caching of active Installs from Catalog to Root, to clarify
ownership
- expose download status on Install
- adjust Delegate signatures to pass more information

Add a 4th layer to the sun (next to disc, inner halo and outer halo). While the inner/outer halos change with atmosphere conditions, the new layer is supposed to represent the effect of blinding brilliance - ideally it adds a suitable ray structure to the sun. The effect is most prominent in space (where I'm most keen on seeing it admittedly) because there all atmospheric halo effects are absent and we end with a really unrealistic white disc.

PropertyObject: enable creation of property
add a create-flag to the node() method of a PropertyObject,
defaulting to false to maintain existing behaviour.
This could be used to add a listener to a non-existing property
without having to write a dummy-value beforehand.
Usage:
myPropertyObject->node() returns the corresponding node or NULL if
does not exist or has not been accessed before.
myPropertyObject->node(true) returns the corresponding node, never NULL.
If the property does not exist, it will gets created.

Nasal: add an naRef to ghosts to allow for proper gc of dependent objects/ghosts.
This allows for binding the lifetime of any nasal object to
the lifetime of a ghost. Otherwise circular references from
objects saved within the ghost would prevent the ghost from
being garbage collected.

Make expiry time for paged models settable from props
Our paged models used the default minimumExpiryTime of zero seconds
which caused frequent stutter with AI traffic loaded.
This patch sets the minimumExpiryTime to 180 seconds, more than enough
to hold the models in memory during a full standard rate turn.
The property to set the expiry time is

Precipitation updates from ThorstenR
Since the consensus seems to be that the precipitation clipping issue is with the panel code, attached is my proposed update for the precipitation system in SG and FG
* without corresponding control structures in FGData it falls back to default, except I have fixed an inconsistency in freezing behavior - previously rain changed suddenly to snow when the temperature dropped below zero, but the reverse transition was dragged out and gave odd visible motion with the wind as snow gradually changed back to rain with the particle speed not well defined. Now both transitions are sudden. And I see no more particles flow against the wind
added to Environment/environment.xml, the new system allows to switch more detailed management on. This provides
* explicit setting of rain droplet size and snow flake size by the weather system
* automatic sqrt(r) scaling of the vertical speed of raindrops
* automatic transition to snow when freezing for small droplets but hail for large droplet sizes (looks like snow, but has different particle dynamics)
* an illumination scaling factor to dim the precipitating based on the light we have in the scene (I still need to devise a property rule to set this automatically)
The clip distance is also exposed now and considered at startup of the system - might be useful for e.g. airships when the gas bag provides rain cover (?) or to be simply off for open airplanes

Set sun color below horizon
Thorsten Renk:
The following patch sets the sun color to alpha=0 when
the sun is below the local horizon, removing the oddity
that the sun is seen 'through' the terrain when the terrain
at large distance is rendered by the skydome.
Stuart has improved the UniformCache approach, here are his
changes:
- We have a UniformCache so that each unique Uniform is only created once
- As part of the UniformFactory we also have a queue of listeners that are still to be added
- When the main thread sends an Update node visitor across the Effects,
all queued listeners are de-queued and added.

Partial fix for crash in SGPropertyNode::fireValueChanged
The effect system used Listeners on property nodes to get the values
for shader uniforms. These listeners get deleted by an osg thread
causing access to freed memory when this happens while the main thread
calls fireValueChanged.
This patch changes the update method to polling for scalar properties.
This isn't 100% threadsafe, too. But at least it does not crash anymore.
