Canvas: use weak pointer to protect parent element access.
Using a weak pointer is the best way to ensure no invalid
pointer is used. This also fixes a possible crash in
simgear::canvas::Element::getParentStyle on destructing
canvas elements.

Package support progress
- check the catalog version explicitly when refreshing
- handle packages with distinct dir name / primary ID correctly
(requires an updated catalog XML format)

Package support hacking
- 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.
memory reduced tile loading.
- do not save the TileGeometryBin and matcach in the randomObjectCallback
- recreate matcache, and get TileGeometry from scenegraph
- split obj.cxx into three distinct files - loadBTG, load surface geometry, and load tile details
- includes fix for sceneries that have missing materials

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
/sim/rendering/plod-minimum-expiry-time-secs

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.
