closes #99

[jw3]

This adds a formatting option to remove semicolons. I did not realize they were not required in Typescript... any objections @arosien @Shanedell ?

This also adds a setting for final newline in file so those are synced up

"files.insertFinalNewline": true

@jw3 Semi-colons are not required but I believe for the most part they are put in usually. But if its not a big deal I have no problem whichever way.
