Notification system

[Mondei1]

Is your feature request related to a problem? Please describe.
Currently we have that fullscreen error which takes obviously the entire screen to display one error. We need to change that.

Describe the solution you'd like
We should implement a small notification system to display errors, simple messages and progress. The types are:

• Message
  • Error
  • Info
  • Warning
• Yes/No(/Later) question
• Progress bar

As additional arguments:

• permanent: boolean The notification stands till the user clicked on in otherwise it's to find in the Notify Center (or other name) default: false
• sound: boolean Plays a sound on pop-up. default: true
• visableFor: number Seconds how long the message appears till it goes to the Notify Center. default: 4
