Work-around for crash

When not using geckofx the program was still initializing xulrunner
causing the crash.

WARNING: When GeckoOption is OFF you will NOT have full functionality.
In particular BROWSE NOTES will NOT work.
REMOVE after geckofx29 is upgraded

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

The S/R Dialog's Settings link launches the Internet server
settings which require PalasoUIWindowForms.GeckoBrowserAdapter.dll.
Chorus/libpalaso usage of Gecko was recently changed and this
assembly was added and we missed adding it to the package.
