SQL icon
**Describe the requested icon**
We would like a SQL file icon, since we are making a folder tree and would like to give the .sql files a nice icon

**Screenshots**
The icon should preferably look like this (From flat icon), but if you would rather do it the way you have made your other file icons, that is fine too
