Demo task manager app

Tasks manager app is implemented on three different architectures:

1. client-server architecture: requires a server to be hosted somewhere on the internet and users are required to sign up for the service. Data is stored on the server. demo

2. client-local: no sign up required, a static website is hosted somewhere on the internet and all data is stored on the browser's local storage. Multi-device synchronisation is achieved by manually exporting state through a file and importing it on the other device. demo

3. client-p2p: no sign up required, a static website is hosted somewhere on the internet. This implementation uses textile.io's ThreadDB, an IPFS based technology. Synchronisation is achieved by exporting the private key of the user(~128 bytes) and importing it on the other device. Users can also migrate their 'silo' from one provider to another or just self-host. demo

These are demo implementations and shouldn't be used as references. The whole thing was put together in under a day so they are not idiomatic. I'm surprised it even works :D
