Fix insert command and cleanup resulting text
Fix insert command and cleanup resulting text

The 'insert_text' command wasn't working on my Sublime Text 3 install, so I did some digging
around until I found an example using the 'insert' command with a 'characters' parameter
instead. I tried this, and it works, so I made the change.

Additionally, I was having problems with the auto_indent pushing each successive line
inserted one more tab stop to the right, so I disabled that setting temporarily while
I inserted the text.

Finally, to try to improve the cleanliness of the source a bit more, I added commands
to reindent and translate tabs to spaces.
