I has try to improve some things in core (/computer pages ...) and find some 'old' code

There are a lot of deprecated code blocks.
 
@deprecated as of 1. --> will find 179 results in 87 files
and 
@deprecated as of 1.286 –> will find 30 results in 22 files.
 
I propose to remove all code deprecated since 1.* , because on April 20, 2016 version 2 was released (google search). That means ever body has ~ 6 years to adapt plugins ... .
 
When the community agree I can start with clean up. But please get feedback here which version shall I care.
 
pro:
This will helps to make the core code more:
+ readable
+ maintainable
+ faster build process
 
contra:
+ some old plugins might no more works
