Fix #599: SSASCMDLETS module cannot be loaded

This change fixes an issue where SQL's SSASCMDLETS module cannot be loaded
into the interactive console because the host currently has a pre-1.0
version number.  For now we will fix this by reporting our version as 1.0
since we're pretty close to 1.0 anyway.
