The editor can be specified:
* via "ExternalEditor" setting in settings.xml
* via LL_SCRIPT_EDITOR variable
Removed obsolete XUIEditor setting in favor of the new one.
Added accessors to get platform-specific process ID from LLProcessLauncher.
Added an optional "debug" argument to LLPluginClassMedia::init() and LLPluginProcessParent::init() (defaults to false).
Mac only: made the state machine in LLPluginProcessParent::idle() open a new window in Terminal.app with a gdb session attached to the plugin process upon successful launch.

Some branch shenannigans in the pluginapi_05 branch caused this to become a two-part merge.
