Added development mode for running app in browser with sql.js

[nextlevelshit]

I've added sql.js, changed db connection depending on ionic platform (cordova|browser) and shimmed sql.js as global module inside webpack configuration.

Thank you for this contribution. I understand, that it makes sense for most development setups to have the option to run in the browser. But these examples should be a simple starting point, so I'm not sure, it should be included out of the box. Also, I'm not sure, that this project needs a yarn.lock.

yarn.lock is at all not need, but *.lock files were not excluded in gitignore, so I was not sure to do it by myself. In any case it is recommended to use yarn instead of npm, but this topic should not be affected in this Pull Request.

Concluding from your argumentation, Ionic apps are only deployed on devices and in production mode. This sounds unusual for me. It is uncommon to develope while emulating or running on a device. Nevertheless most time the code will be deployed in development mode, so it is necessary to have the possibility to use TypeORM also in browser.

This should be a standard. Otherwise nobody will find a working example for that combination of webpack, ionic and TypeORM. So let's start providing something more lifelike. Nobody developes in prodcution mode only.

I'm not saying, that it is unusual to use ionic serve. But the idea of these examples is to give a minimalistic starting point, but I agree, that it is helpful. If you address my other comments, I can merge it.

I will do, thanks.

[daniel-lang]

Did you test, that it still works when running ionic serve?

For sure @daniel-lang. Everthing runs perfectly. I've tested on Ubuntu 17.10.
