[Improvement] Switch to Typescript #27
Description
After the last incident with the minifier package we were using, minify (more details here #26), releases after 5.0.1 aren't being minified.
So, to improve overall project structure (since the project has grown a lot since its start) and to minify the final code, we can ship the compiled JS after passing through the TypeScript compiler. Two improvements at once!
This issue will remain open till we have some time to work on it.
