Disabled saving notifications to disk because the load code hasn't worked for months, it spams the logs, and it hits the disk.

These changes had been made last month, but got smooshed.

Added a version field at the beginning of inventory cache files.  If version field is not found or does not match expectected value, then the cache is discarded.  In 1.23, the version line triggers a warning but is otherwise ignored.

For EXT-2335 Diagnose warning spam: "LLInventoryPanel::buildNewViews called with invalid objectp->mType"

Trivial fix to just ignore reading in items that have unknown/none asset type.

problem was caused by triggering updateMeshTextures() every time visual params
or textures were changed on your base avatar object. The latest structure
makes the parameters and textures in the wearables authoritative, causing them
to be copied to the avatar on a regular basis. This resulted in way too many callbacks
to be registered while waiting for baked textures to be uploaded.

Fixed by removing many calls to updateMeshTextures() and ensuring that it gets called
every time an appropriate param or texture actually changes, or a wearable gets
added/removed. This appears to cut the number of callbacks to a reasonable level.

- we'll be managing its state rather manually, not necessarily conforming to 'toggle' semantics.

Various trivial UI behavioral changes for disabling/enabling old/new floaters when bringing up properties of objects/items.
This is to make the UI behavior compliant with the Inventory Panel MVP.

Also added missing sidepanel_task_info.xml (although this is not actually enabled for viewer2.0).

Don't have LLVoiceClient manually poke the nearbychatbar's 'speak' button's visual state as a special case
- all speak buttons will soon know how to poll (sigh) the ptt state, with more reliability.

- because on second thoughts, there's not much wisdom in carrying probably-not-tested-for-years code around 'just in case'.

randgauss.h isn't *really* used by the viewer - remove #include and move it to llmath with ll-header naming convention.

I18N: 2 nodes in panel_preferences_privacy.xml cant be localized because it has no name=

It was failing to open due to an unknown string and the L$5 button was
labelled incorrectly (it said L$1).

and Buy Land floaters.

We now check for a new estimatedLocalCost key from the XML-RPC server,
which provides the estimated cost in the user's local currency, e.g.,
"US$ 10.00" or "10.00 Euros". Note: the server is not currently
sending this information.

The previous codepath still exists and should be unaffected. That is,
we will continue to check for an estimatedCost key from the server with
a value specified in US cents. We give precedence to estimatedLocalCost
though and may want to remove this code once the international billing
server changes go live.

In the --autologin case, gFirstname, gLastname were validly set from
gSavedSettings, but at the last minute were overwritten with empty strings
from gLoginHandler. Only perform those assignments if gLoginHandler has
non-empty strings to contribute.

This code seems to work on some objects and not on others.  I suspect I'm not doing something quite right in LLVOVolume::getApproximateFaceNormal().
