Added a few new snippets

Diraj et al,
I added a few new snippets that I found useful. Perhaps you will like them as well, and merge them into the package.
The block _if_ and _for_ loop snippets add the snippet around whatever code you have selected. I thought about adding the selection inside the existing snippets that you already have, but if you do not select anything, the snippet it adds a blank line where that code would be.
Optionally, we could add _if_ and _for_ blocks that would automatically surround whatever line of code the cursor is currently sitting, rather than selected. I liked that idea as well.
Let me know what you think.
Thanks man
DTodd
