1. Added error checking for Lineout parameters passed via Query (eg from CLI or Query Window, not Lineout tool). Resolves #1292
2. Removed extraneous Logging of Picks/Queries/Lineout. Resolves #1298

As a consequence of looking into the two above:
3. Added logging for GetQueryParameters.
4. Added logic to handle GetQueryParameters for Lineout.
5. Updated cli Lineout method to handle named parameters the same way that Query("Lineout") does.
6. Reduced number of times SetQueryFloatFormat is called when using the gui to do a Query.  Noticed it cropping up during Command Recording every time a query was performed, regardless of whether or not the format had changed in between.
