Update mssql.JSON (#1803)

I modified lots of snippets to include the database name so that the user can additionally tab through the database name. I made some quality of life change for the user.  I normalized and standardized snippets to look more like one user created the file rather than each script taking on various flavors from the contributors. I tried to write the comments in the snippets in the same style at the majority of the snippets.  I added highlighting in key areas that were missing it or were not replacing the comments. Additionally there was no snippets for sqlCreateIndex and sqlCreateTempTable which I find standard for SQL users.  Let me know your thoughts! No trying to offend anyone if I changed your code.
