Added slplugin-objc.mm.
Made SLPlugin do the cocoa setup during initialization, and create/delete an
autorelease pool each time through its main loop. This should make plugin code
that's using autorelease correctly not leak.
Fixed a bug in the version of setupCocoa() used in the viewer (it was never
setting its "inited" variable).
Made SLPlugin into a bundled app on the Mac (this is apparently necessary for the plugin's window to be allowed to get focus).
Changed the Info.plist key SLPlugin uses to keep itself out of the dock from LSBackgroundOnly to LSUIElement (this allows it to get focus and display UI).
Added some Mac-specific code to slplugin.cpp to manipulate window layers and bring the plugin process to the foreground when something in the process opens a window, and to bring the viewer to the foreground when the last window in the process is closed.
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.
