Request that will allow SublimeREPL to have sqlcmd for use with Microsoft SQL Server

Hello,

I love this plugin!  Thank you for creating it!  This will get me to finally buy a Sublime licence. I've been waiting to figure out a solution to running my database queries and getting results back into Sublime in a seamless way.

My changes add sqlcmd as a repl. This is for use with Microsoft SQL Server.  The change is rather small. Aside from my minor edit and addition of a new repl config folder The user will also need to create a TSQL language for Sublime. All I did was copied the existing SQL folder that comes with Sublime named it TSQL and updated all references to .sql to .tsql within the SQL files.  I did this because I plan on creating repl for Oracle SQLPlus and PostgreSQL psql tools in the future and couldn't see any other way to make sure the correct repl is used. Please let me know if you have any questions. I feel this will be a useful addition to those of us who have come to love Sublime and want to use it for database related work.  Attached is an example of the change be put to use(database bliss).

Thanks again,
