propagate the parent app's OSUserAppDir (i.e. ~/.secondlife/) all the way down to plugins, if they need persistant user data/settings (like the webkit plugin needs a place to put its cache).
Enabled CPU limit setting by default (set to 100% of 1 CPU).
Lowered default limits on plugin priorities: 2 normal+, 4 low, 8 total.
Limit on total number of instances now only applies to inworld media -- media instances in the UI (such as the help browser and search) don't count toward the limit. UI media will still bump inworld media down from normal/low priority, though.
Several improvements to plugin manager debug code in the nearby media list.
Don't load unloaded instances that are at PRIORITY_SLIDESHOW or PRIORITY_HIDDEN (they don't get unloaded, they just won't be loaded unless they're at higher priority).
Added LLViewerMediaImpl::isPlayable(), which indicates whether an instance would be loaded if it were high enough in the priority list (taking into account autoplay and current load state). Priority algorithm now takes this into account.
Fixed a couple of issues with approximate texture interest calculation and its use in setting priorities.
Adjusted sleep times on low and normal priorities to be more friendly.
svn merge -r 129913:131718 svn+ssh://svn.lindenlab.com/svn/linden/branches/pluginapi/pluginapi_05
Some branch shenannigans in the pluginapi_05 branch caused this to become a two-part merge.
