I found our upload classes were in need of a tune up while researching Issue 896: Animation upload setting causes viewer crash
So I started working to clean up llfloaterbvhpreview which lead me to llfloaternamedesc and the rest of our upload floaters
I ended up pulling the sound upload hack out of LLFloaterNameDesc and into LLFloaterSoundPreview and moving LLFloaterAnimPreview into llfloaternamedesc.*
Updated llviewermenufile.cpp a bit
Removed setUploadAmount from LLFloaterImagePreview and LLFloaterBvhPreview as its purpose is served by LLGlobalEconomy::getPriceUpload and the hippogridmanager too.
Fixed an issue with floater_animation_anim_preview.xml using [AMOUNT] instead of [UPLOADFEE] for its label.
I'd say this might fix Issue 896, I certainly can't reproduce the crash I was having when testing for it anymore.
