Growl for Windows  2.0.9

- set NoImpersonate flag on custom installer actions (in hopes of avoiding some 2869 errors)
- merged setup.exe and Growl.msi into a single GrowlInstaller.exe self-extracting file
- added coalescing support to native Plain, Smokestack, and Standard displays (queueing displays such as Toast and Visor do not support coalescing)
- fixed issue where application icon and default notification type icon were not updated if they were currently selected in the UI when a re-register request came in
- fixed issue where application was cut-off if it was longer than one line (on Applications tab)
- Growl now saves forwarder/subscription pref changes to disk immediately instead of only when Growl exits
- fixed issue where settings specified in growl.exe.config were not honored on the first run
- updated iTunes plugin to support coalescing (one notification on screen at a time)
