Switch nodemon over to tsc-watch, enable incremental builds.

[Sacro]

Now tsc 3.4.1 is out, we can use some of the new features. I've left the tsconfig files as-is aside from excluding the "dist" folder.

Is tsc-watch library mature enough to recommend its usage in the starter project? Results look promising and we should definitely take advantage of the new incremental builds in TS. I'm slightly afraid about tsc-watch though.

[Sacro]

Looking at the tsc-watch bugs, it seems it does have issues with non English locales, that's not great. I'll see what alternatives there are.

[kamilmysliwiec]

What about running tsc --watch and nodemon concurrently?

[Sacro]

That would work, but the nice thing about tsc-watch is it waits for the build to be succesful or to fail before moving on. Using wait-on alongside concurrently might be a nice solution

[kamilmysliwiec]

True. Anyways, tsc + nodemon sounds like a more stable integration + is much faster. Should we move with this one for now? :)

[Sacro]

Sounds good to me

I'll close this and we can move to #124
