MSSQL and mssql.initial can't create identities

[JabbaTek]

It turns out that there is a problem in the mssql.initial file which contains the scripts for creating table in an mssql database for RoundCube Mail.  

When the script created the Identities table, it leaves out one column (html_signature).  Once i added this column manually to the table, I was able to create an identity so I cound send email using RoundCube.
