Change whitespace for .ts files

We recently noticed and agreed that typescript files should follow
the same standard as javascript files, i.e. indented by 2 spaces
instead of tabs. This change applies the new rules to all .ts files.
Change whitespace for .htm* files

A while back it was noticed that HTML files should also be indented
by two spaces. This change applies the new rules to all .htm* files.
Change whitespace for .tmx files
