Reviewed with Leyla.

Main change is pointing install.xml for Windows to new version of LLQtWebKit that has DLLs with no manifest as per recent build change.
Tweaked bookamrks for test app too.
Finally, added fix for DEV-41392 (Home URL Preview should be next to the Home URL)

DEV-41787 Media Auto Play controls were removed from prefs.  Also made auto play override prim settings.

Two part fix: prevented the copying of wearable parameters to the avatar to trigger a rebake.
Then: Called wearableUpdated every time a wearable was added/removed/replaced and ensured it properly invalidated the composite

Confirmed working fix on developer machine.

Code reviewed by Seraph.

Changes to match new version of llqtwebkit -- passing modifier keys through to most user events and using new scroll wheel event.

For EXT-1863 : "Wear" and "Take Off" for items should be properly greyed out depending on item worn state

These textures are used during terrain rendering.  Not having them also
breaks invisiprims in an interesting way.

for testing purposes.

removing name attribute stopped "Missing String" message
appearing - don't know why - asking around.
