WS-83 missing assembly causes crash in S/R Dialog

In previous change (1beddfb), the missing assembly
(PalasoUIWindowsForms.GeckoBrowserAdapter.dll) was used in the
build, but not included in the package.  This change includes
the assembly in the package.

WS-84 WeSay.App crashes on shutdown in XulRunner

We used to have code in WeSay to Shutdown XulRunner so that it
didn't hang on shutdown.  Now it seems that this forced shutdown of
XulRunner is causing a crash when the nsCycleCollector is cleaned up.
