/*
* description:
* Determine a path to tab.htm, which is
* loaded into a browser window to start
* Netcaster by checking
* the following locations in order:
* $HOME/.netscape/netcast/tab.htm
* $MOZILLA_HOME/netcast/tab.htm
* Version Registry via VR_GetPath()
* fe_GetProgramDirectory()/netcast/tab.htm
*
* The reason for precedence is as follows:
* $HOME first. Preferences set in a user's
* $HOME override everything else.
* This allows users some chance of running in
* the case where the system admin won't install
* Netcaster in globally accessible location.
* This can also be useful for debugging purposes.
*
* $MOZILLA_HOME is now recommended as the standard
* for finding Communicator and related components.
* It comes next.
*
* The registry should get set correctly during ASD install.
* However the registry's role in tracking versions has
* been emphasized over its role in tracking location.
* (although you can't have the former without the latter).
* Rumor also has it that some people are in the habit
* of deleting the registry to fix problems, so it
* may not always be available.
*
* Last resort is to do our best effort at determining
* where Communicator was invoked by getting the program directory
* by looking at the invocation path.
*
* returns:
* On success returns a path to tab.htm
* On failure returns NULL
