* Use "lib" in tsconfigs instead of "target".
Only add "dom" to libraries that need it. This is determined by a script, so many libraries that have "dom" maybe should not.
* Update new-package and readme
* Add back "target" where necessary
* add apex.js
* 4 spaces
* fix `implicitly has any type`
* match the style of tslint.json
* make `event` and `context` not optional
* avoid annotating the types of callbacks manually
