D.Tube alternative - Implementing Account functionality

Hi everyone,
As already mentioned in this post: https://steemit.com/d-tube/@labomba/alternative-for-d-tube I am working on an alternative for d.tube.
For those who are interested in my progress, this is the current state, you may read further:

I implemented a simple login functionality. Identification is currently performed with accountname and private posting key. Steemconnect v2 will be implemented later!

After successfull authentication, you may notice the difference in the Appbar.

Accountdata is saved for this session and will be deleted as soon as you will leave then webapp.
Thank you for reading!
Have a nice day !
