Took out some ugly case statements and stuck those functions into the asset dictionary instead.  This makes the code a lot more centralized/extensible since if we ever add assets, it'll be clear that their fetch/knowable fields need to be added (versus that logic being in some obscure case statement).

gAgentAvatarp pointer was being checked for null instead of the local avatarp.

Moved LLLibraryOutfitsFetch and LLInitialWearablesFetch

These functions are defined in LLInventoryFunctions.h but their implementation is in LLInventoryBridge...  moved everything to LLInventoryFunctions.

Fix for S32/F32 mismatch.

Moved all the LLInventoryModelCOllectFunctors from LLInventoryModel to LLInventoryFunctions

cleaning up a merge conflict where HG didn't quite do the right thing.

LLAgent.* cleanup
Also took out some constants from llagent.cpp that aren't being used.

Fixed several areas of code that were not multi-wearables enabled.
Specifically allowed for the wearing of created outfits that had links to
multiple items of the same type. Such outfits can be created by dragging
multiple items of the same type into an unworn outfit folder. When you
wear the outfit, all items (up to 5 per type) should be worn. Does not
affect right-click options or other buttons.

Took out unnecessary #includes from llagentcamera.*

Orbit/Pan keys were already in llagentcamera.  Pulled alt/walk/left/up/yaw/pitch into llagentcamera.

Created LLInventoryModelBackgroundFetch file for handling background fetch.

The issue here is that initBrowserWindow() was doing the wrong thing if it got called after the set_user_agent message was received.

Made the handler for the set_user_agent message save the string in a member variable (mUserAgent).

Initialize mUserAgent to the default string in the MediaPluginWebKit constructor.

initBrowserWindow() now sets the user agent string from mUserAgent instead of from a literal.

Superficial cleanup to change all typedef std::vector<LLUUID> to use a common typedef uuid_vec_t instead.

This bugs me in a minor way.  Did a search-and-cleanup on various swear words.

No longer explicitly deleting gAgentAvatarp due to reference counting.

Fix for cleaning up gAgentAvatar on app shutdown.
